The 30-second answer
This is a class of two true pairs, not four individual ships. One refit, in 2019, is the entire reason one pair scores a few tenths higher than the other — everything else about these four ships' dining runs on the same closed roster.
Every Millennium Series ship seats its entire included tier in a single main restaurant — Metropolitan, Cosmopolitan, Trellis or San Marco, depending which hull you're on. Millennium and Summit's rooms went through the same 2019 redesign; Infinity's and Constellation's did not. That one fact, more than any other roster difference in this class, is what separates a 7.4 from a 7.3 here.
How dining works across the Millennium Series
This class runs on the same Seabound Dining Score rubric as every other Celebrity guide on this site, but a few things about how its roster is structured are worth knowing before you read the tables below.
Eight categories, the same weights we use fleet-wide. Included – Full Service 25% · Specialty Dining 20% · Variety 15% · Quality Ceiling 10% · Value 10% · Casual & Quick Dining 10% · Special Experiences 5% · Suite & Restricted Dining 5%. Celebrity's two-restaurant suite structure earns the same weight here as it does everywhere else on the site.
One main dining room, not a system to navigate. Celebrity's newer Edge Series runs four restaurants as open seating under one umbrella; every Millennium Series ship instead seats its included tier in a single room — Celebrity Select Dining, a choice of fixed early or late seating or anytime open seating, breakfast and lunch on sea days, dinner nightly. We score it as Included – Full Service, the same category label used everywhere else on this site.
This is the oldest class in Celebrity's fleet, and it shows in the specialty tier, not the main dining room. Millennium debuted in 2000, Infinity and Summit in 2001, Constellation in 2002. None of the four carries a marquee signature restaurant to rival Celebrity's newer ships, and the specialty roster tops out at Tuscan Grille, Sushi on Five and Le Petit Chef — a real, honest step down from what Solstice and Edge Series ships carry, and the reason this class's Specialty Dining and Quality Ceiling scores sit lower across the board.
Le Petit Chef now runs inside each ship's former Qsine space. Celebrity's theatrical, animated tabletop-projection dinner has effectively replaced Qsine fleet-wide on this class; we treat the two as one venue, not a separate tasting menu layered on top of a separate theatrical dinner.
Chef's Table by Daniel Boulud runs on all four ships identically. It's a fleet-wide fixture of this class, listed on each ship's own current overview page, and it plays no role in separating one hull's score from another's.
Representative pricing checked August 2026. Room service carries a 20% automatic gratuity fleet-wide, with a complimentary continental breakfast from 6–11am. Daily automatic gratuities — a separate line item from that 20% purchase-based charge — run approximately $19.50/day in standard staterooms, $20.50/day in Concierge and AquaClass, and $24.50/day in The Retreat. Specialty dining and packages price dynamically and vary by sailing; verify current figures for your cruise before booking.
Find your ship
Two questions. Because this class is really two true pairs, this tool sorts you into one of two groups — the 2019-refit MDR pair or the unrefit MDR pair — and tells you what that choice actually changes at the table.
Which Celebrity Millennium Series ship fits how you want to eat?
Answer both and we'll name a ship and explain why — with its true twin, not just a winner.
Where the four ships split
Almost nothing else diverges in this class — that's the point. Two texture details are worth flagging, plus one venue each ship carries that the other three don't score at all.
| Venue / detail | Millennium · Summit · Infinity · Constellation | Payment |
|---|---|---|
| Cellar Masters Wine-pairing experience served alongside Japanese small plates from Sushi on Five. Present on all four ships as alternative-dining texture — not scored as its own Specialty Dining venue. | MiSuInCo | Mixed |
| Michael's Club → Retreat Lounge Infinity's January 2024 refit converted Michael's Club into a new Retreat Lounge — ship character, not a dining venue. | MiSuInCo | — |
| Qsine name retirement Summit retired the Qsine name specifically after 2019, moving straight to Le Petit Chef in that space. | MiSuInCo | — |
Cellar Masters is the one recurring detail worth knowing about, and it's identical on all four ships. It pairs wine flights with small plates pulled from the Sushi on Five kitchen, and it's real, current and fleet-wide — we just don't score it as a separate Specialty Dining line, the same way this project treats similar wine-bar hybrids elsewhere.
Two venues appear on individual ship pages but not in this class's scored roster at all. Millennium's "Juice Bar" doesn't appear to offer a substantial food menu beyond juices and smoothies. Constellation's "Sunset Bar" is a cocktail and live-music venue on Celebrity's own current description, not a dining spot. Neither counts toward either ship's score.
The specialty and casual concepts unique to Celebrity's newer Solstice and Edge Series ships — the marquee restaurants, the gastropub-style casual venues, the deck-top grilling concepts — do not exist anywhere on Millennium, Summit, Infinity or Constellation. This class's specialty tier begins and ends with Tuscan Grille, Sushi on Five, and Le Petit Chef.
Suite & Restricted Dining — the class's tightest category
Luminae and Blu run in parallel on every Millennium Series ship, and the tiny gap that does exist here runs opposite the class's main pattern — the two ships without the 2019 MDR refit score marginally higher.
Luminae, for Retreat suite guests, and Blu, for AquaClass guests, operate on all four ships — the same two-restaurant suite structure Celebrity runs fleet-wide. Millennium and Summit score 8.8 here; Infinity and Constellation score 8.9. It's a genuinely marginal gap, and it runs the opposite direction from Included – Full Service.
The reason is specific, not incidental. Infinity's January 2024 refit expanded Luminae's seating capacity and converted Michael's Club into a new Retreat Lounge, and Constellation's September 2024 refresh touched the same Retreat/Luminae footprint. Neither refit reached the main dining room — that's the real trade: Infinity and Constellation gave up an MDR redesign in exchange for a marginally stronger suite-dining footprint.
Either way, this category sits below both Solstice's flat 9.0 and Edge's 9.1 — correctly, reflecting this class's older, smaller suite-dining footprint rather than any single ship's shortfall.
The specialty tier — genuinely thinner than Celebrity's newer classes
Specialty Dining scores an identical 7.1 on all four ships. That flat number isn't a coincidence — it reflects a roster that simply doesn't vary from hull to hull, and one that tops out lower than what Solstice or Edge Series ships carry.
Every ship in this class runs the same three specialty rooms: Tuscan Grille, Sushi on Five and Le Petit Chef, plus the fleet-wide Chef's Table by Daniel Boulud. There's no ship-specific swap here the way there is on Celebrity's newer classes — no ship trades one specialty concept for a different one, so the category simply doesn't move.
Quality Ceiling splits along the same 2019-refit line as Included – Full Service, but in reverse: 6.9 on Millennium and Summit, 7.1 on Infinity and Constellation. No ship in this class carries a Forbes Travel Guide-rated specialty restaurant right now, and none carries anything close to a marquee signature room on par with Celebrity's newer classes — that absence, not any one ship's cooking, is what caps this category across the board.
Net: this is a narrower specialty ecosystem with a lower ceiling than Solstice and Edge Series, despite retaining Celebrity's strong baseline execution. Tuscan Grille, Sushi on Five and Le Petit Chef are consistent, reliable rooms on every ship in this class — there just isn't a fourth or fifth specialty concept layered on top of them anywhere in the fleet's oldest class.
Special Experiences — identical, and the class's lowest-weighted category
All four ships score 6.9 here, the lowest of any category in this class alongside Quality Ceiling on two of the four ships. Le Petit Chef and Chef's Table are real, fleet-wide draws — there just isn't a third format layered underneath them.
Le Petit Chef, hosted in each ship's former Qsine space, is this class's one true theatrical dinner format, and it runs identically on all four hulls. Chef's Table by Daniel Boulud sits alongside it on every ship too. Neither venue is a differentiator between ships in this class — both are simply present, everywhere, at the same standard.
Cellar Masters adds real texture here without moving the number. Its wine-and-small-plates format is a genuine special-occasion pick on all four ships, but as alternative-dining color rather than a separately scored venue, it doesn't push any single ship's Special Experiences score above its sisters'.
The honest read: this category reflects this class's narrower ceiling more than any other. Solstice and Edge Series ships layer two or three distinct special-experience formats on top of each other on their strongest hulls; every Millennium Series ship has exactly one, run consistently well but not multiplied.
No ship in this class currently holds a Forbes rating, but the four ships got there four different ways. Millennium's own Forbes listing reads "Soon to be Rated" — a pending status. Summit was actually named a Forbes Five-Star in the inaugural 2023 cruise ratings, but that recognition has since lapsed and Summit is absent from the current list entirely — a past distinction, not a current one. Infinity and Constellation have never appeared on a Forbes Travel Guide list of any kind. Treat these as four separate facts, not one shared footnote.
Seabound Showdown · the full class
Eight categories, one rubric, four ships. These are ecosystem scores, not averages pulled up from the venue tables above — and both headline ties hold across every single row, not just the total.
| Category | Weight | Millennium | Summit | Infinity | Constellation |
|---|---|---|---|---|---|
| Included – Full Service | 25% | 7.6 | 7.6 | 7.4 | 7.4 |
| Specialty Dining | 20% | 7.1 | 7.1 | 7.1 | 7.1 |
| Variety | 15% | 7.2 | 7.2 | 7.2 | 7.2 |
| Quality Ceiling | 10% | 6.9 | 6.9 | 7.1 | 7.1 |
| Value | 10% | 7.5 | 7.5 | 7.5 | 7.5 |
| Casual & Quick Dining | 10% | 7.3 | 7.3 | 7.3 | 7.3 |
| Special Experiences | 5% | 6.9 | 6.9 | 6.9 | 6.9 |
| Suite & Restricted Dining | 5% | 8.8 | 8.8 | 8.9 | 8.9 |
| Seabound Dining Score | — | 7.4 | 7.4 | 7.3 | 7.3 |
Millennium and Summit tie at 7.4, and it is a full, category-for-category tie — not just a matching headline. Every one of the eight rows above matches exactly between these two ships. The 2019 Celebrity Revolution refit redesigned both ships' main dining rooms, Metropolitan and Cosmopolitan, and the two ships share the same dining lineup — their main dining rooms differ only in name and decor.
Infinity and Constellation tie at 7.3, also category for category. Suite & Restricted Dining reflects Infinity's slightly larger, refreshed Luminae, and both ships land at the same 8.9. It's a genuine tie, born of how close these two ships actually are, not a forced one.
The entire gap between the two pairs lives in exactly two rows, moving in opposite directions. Included – Full Service favors Millennium and Summit, 7.6 to 7.4, because their main dining rooms went through the 2019 refit and Infinity's and Constellation's did not. Quality Ceiling favors Infinity and Constellation, 7.1 to 6.9, and Suite & Restricted Dining favors them too, 8.9 to 8.8 — the flip side of the same story, since both ships' more recent refits went into suite dining instead of the main restaurant.
Every other category — Specialty Dining, Variety, Value, Casual & Quick Dining, and Special Experiences — runs identically across all four ships. Chef's Table by Daniel Boulud, present fleet-wide, has no bearing on any of it.
Every venue in the class
All 14 distinct dining venues, filterable by ship or by how you pay. Every ship carries 11 of them — ten shared fleet-wide, plus that ship's own main dining room — which is why this class's roster barely varies from hull to hull.

Celebrity Millennium Series dining FAQ
Are Celebrity Millennium and Celebrity Summit really identical on dining, category for category?
Yes — both ships got the full 2019 “Celebrity Revolution” main dining room redesign, Millennium's Metropolitan Restaurant and Summit's Cosmopolitan Restaurant, and every one of the eight scored categories lands on exactly the same number for both ships. Millennium and Summit share the same dining lineup — their main dining rooms differ only in name and decor. Millennium and Summit both finish at 7.4.
Is Celebrity Infinity really tied with Celebrity Constellation, or is that just a rounded headline?
It's a true tie, not just a rounded one. Infinity's January 2024 refit expanded Luminae and added new Retreat suites, and Constellation's September 2024 refresh touched the same Retreat/Luminae footprint — both are suite-focused updates that left each ship's main dining room untouched, and both land in the same place after rounding: 8.9 on Suite & Restricted Dining, 7.4 on Included – Full Service, and identical scores on every other category. Both finish at 7.3.
Why do Millennium and Summit outscore Infinity and Constellation at all?
One thing, and one thing only: the 2019 Celebrity Revolution refit touched Millennium's and Summit's main dining rooms and never touched Infinity's or Constellation's. Metropolitan and Cosmopolitan came out of that refit redesigned; Infinity's Trellis Restaurant and Constellation's San Marco Restaurant did not. That's the entire reason Included – Full Service scores 7.6 on Millennium and Summit against 7.4 on Infinity and Constellation, and it's the only real gap driving the 7.4-versus-7.3 headline split in this class.
Does every Celebrity Millennium Series ship have Chef's Table by Daniel Boulud?
Yes — all four ships. Chef's Table by Daniel Boulud runs on Millennium, Summit, Infinity and Constellation alike, so it plays no role in why any of these four ships scores higher or lower than another. The real driver of this class's one real gap is the 2019 main dining room redesign, not Chef's Table.
Do any Celebrity Millennium Series ships currently hold a Forbes Travel Guide rating?
No, not currently, and each ship's story is different. Millennium's own Forbes listing shows “Soon to be Rated” — a pending status, not an active award. Summit was named a Forbes Five-Star in Forbes's inaugural 2023 cruise ratings, but that recognition has since lapsed and Summit does not appear on the current list at all. Infinity and Constellation have never appeared on a Forbes Travel Guide list in any capacity. None of the four should be described as currently Forbes-rated.
Is this class's dining weaker than Celebrity's Solstice or Edge Series ships?
It's a narrower specialty ecosystem with a genuinely lower ceiling, not weaker execution. Millennium Series tops out at 7.3–7.4 against Solstice Series' 7.8–8.1 and Edge Series' 7.8–8.6, mostly because this class carries no marquee signature restaurant on the level of Celebrity's newer ships, and no ship in it holds a current Forbes Travel Guide rating. But the baseline — Celebrity Select Dining, Tuscan Grille, Sushi on Five, Le Petit Chef, Luminae and Blu — still runs at a solid, consistent standard fleet-wide. Call it a smaller dining footprint, not a downgrade to avoid.
