A proper one-for-one buffet deal can cut a hotel lunch price in half, but the mechanics—which bank cards work, which sessions qualify, and how long the offer lasts—vary significantly between the two Carlton Hotel properties in Singapore. This guide breaks down the active 1-for-1 buffet promotion at Café Mosaic (Carlton Hotel, Bras Basah) and Plate (Carlton City Hotel, Tanjong Pagar), using official bank pages and hotel websites to clarify exactly what you pay, when you can dine, and which credit card partners actually deliver the discount.

How much does Carlton Hotel buffet cost?

The standard adult price for the Flavours of Hong Kong lunch buffet at Plate, Carlton City Hotel is S$62++ per adult on weekdays (Monday–Friday) and S$68++ on Saturdays and public holidays, according to the hotel’s official offer page. Children aged 6–12 are charged S$28++–S$32++, while children under 6 dine free. Seniors aged 55 and above receive 50% off the regular adult price, a policy that applies separately from the 1-for-1 cardholder deal.

At Café Mosaic, Carlton Hotel (Bras Basah), the standard adult price for the Hong Kong Kitchen Lunch Buffet is listed as S$128 per adult in a 2024 YouTube review (the hotel site does not publish a current rack rate). The 1-for-1 deal effectively halves that to approximately S$64++ per adult, though the exact net figure depends on the service charge and prevailing GST.

Operational hours for lunch at Café Mosaic run 12:00 PM–2:30 PM daily; dinner runs 6:00 PM–10:00 PM (last order 9:30 PM). Plate’s Flavours of Hong Kong lunch operates Monday–Saturday, 12:00 PM–2:30 PM.

Tip: The senior 50%-off deal at both venues can undercut the 1-for-1 when a single senior dines alone or in an odd-numbered group. For two seniors, the per-person cost is identical to the 1-for-1 offer.

The bottom line: Standard pricing at Plate starts S$62++ per adult; Café Mosaic’s rack rate runs higher but the 1-for-1 brings it into a similar band. The key difference is the breadth of bank partners—Plate accepts five banks, Café Mosaic four.

What is the Carlton hotel buffet 1-for-1 promotion price?

The effective per-person cost with the 1-for-1 deal depends on which venue and session you choose. At Plate, the weekday lunch price of S$62++ per adult becomes approximately S$31++ per adult when split between two diners on a 1-for-1. Saturday lunch works out to about S$34++ per adult. The Sea & Grill dinner buffet (Friday–Saturday) had a reported 2023 list price of S$118++, making the effective 1-for-1 cost roughly S$59++ per adult, per a 2023 deal write-up on ConfirmGood.

At Café Mosaic, the 1-for-1 applies to the Hong Kong Kitchen Lunch Buffet (daily) and the Hong Kong Seafood Dinner Buffet (Thursday–Saturday). With a standard adult price of S$128, the deal works out to approximately S$64++ per adult for two diners.

The promotion is valid through 30 December 2026, per the DBS Bank promotion page and the Carlton Hotel official site. The same end date applies to both properties.

Credit card partners for 1-for-1

  • Plate (Carlton City Hotel): Citibank, DBS/POSB, Maybank, OCBC, Standard Chartered.
  • Café Mosaic (Carlton Hotel): Citibank, DBS/POSB, OCBC, UOB.
Catch: The 1-for-1 deal applies only to the full adult buffet price. It is explicitly not valid on free-flow beer or wine beverage packages, and cannot be combined with other promotions or senior discounts.

The pattern: Both venues use a near-identical bank-partner model, but Plate offers one additional card option (Standard Chartered) and publishes explicit weekday/weekend pricing, making the value easier to calculate before booking.

Is Colony buffet worth it?

Colony at The Ritz-Carlton, Millenia Singapore is frequently mentioned alongside Carlton Hotel buffets in comparison searches, but it is a separate property with a different price bracket. Colony’s dinner buffet typically runs S$88–S$98++ per adult (based on recent Yelp and TripAdvisor data from 2025–2026), with a 2-hour time limit on peak sessions. By contrast, the Carlton and Carlton City 1-for-1 deals bring effective per-person costs to approximately S$30–S$65++, depending on venue and session, with no published time limit at Plate or Café Mosaic (though Café Mosaic’s dinner last-order is 9:30 PM).

A TripAdvisor reviewer described the Carlton City Hotel Chinese dinner 1-for-1 as “value for money” and noted being “very full when finished,” suggesting quantity-per-dollar is a strength. Colony, however, is widely reviewed as offering a broader international spread and higher ingredient quality, particularly its seafood and carving stations.

Colony vs Plate vs Café Mosaic

  • Price: Colony (S$88–S$98++) vs Plate weekday 1-for-1 (~S$31++) vs Café Mosaic 1-for-1 (~S$64++).
  • Time limit: Colony enforces 2 hours on dinner; no public time limit at Plate or Café Mosaic.
  • Variety: Colony offers a multi-cuisine spread; Plate focuses on Hong Kong–style dishes; Café Mosaic’s Hong Kong Kitchen and Seafood menus are narrower but themed.

Why this matters: If raw value (lowest cost per person) is the priority, Plate’s weekday lunch 1-for-1 is the clear winner. If a broader menu and luxury setting are important, Colony justifies its higher price—but only if you can finish within the 2-hour window.

How to get the best value at a buffet?

Maximising value at a 1-for-1 Carlton buffet comes down to three variables: timing, card choice, and group composition. Here is what the data and diner reviews suggest:

  • Book weekday lunch at Plate. At S$62++ for two diners (~S$31++ per person), this is the lowest effective cost of any Carlton 1-for-1 buffet. Saturday lunch runs S$68++(~S$34++ per person), still competitive.
  • Use the correct card. Plate accepts five banks; Café Mosaic accepts four. DBS/POSB, Citibank, OCBC, and UOB work at both venues. Maybank and Standard Chartered cards only work at Plate.
  • Seniors: calculate the better deal. For a party of two seniors, 50% off each (roughly S$31++ per person at Plate weekday lunch) is identical to 1-for-1. For a party of one senior and one younger adult, the junior diner gets 1-for-1 while the senior takes 50% off—yielding the same total as two 1-for-1 diners.
  • Go early. Both venues operate 12:00 PM–2:30 PM for lunch. Arriving at opening maximizes the eating window and avoids last-order scrambles.
Strategy: The 1-for-1 deal works best for pairs. A group of three adults with one eligible card pays full price for the third diner—consider splitting into a pair (1-for-1) and a solo diner, who can use a senior discount or alternative promo if eligible.

The implication: The best value is not a single venue but a combination of weekday timing, correct card choice, and matching the right promotion to each diner’s age and card ownership.

Where can I get a cheap buffet?

For budget-conscious diners, the Carlton 1-for-1 deals rank among the most accessible hotel buffet options in Singapore. A 2026 MoneySmart roundup lists Plate at Carlton City Hotel as a top Maybank 1-for-1 partner. DiveDeals similarly highlights the Surf and Sear dinner buffet at Plate for Saturday evenings with DBS, OCBC, or Maybank cards through December 2026.

Beyond Carlton, a 2025 roundup on Spend and Save Singapore lists more than 20 cheap buffets starting from S$7 (primarily hawker-level or chain restaurants). However, for a sit-down hotel buffet with table service and a themed menu, the Carlton 1-for-1 promotions at S$31++ per person (Plate weekday lunch) are among the lowest per-person hotel buffet prices available in 2026.

What to watch: The 1-for-1 offers are tied to the promotion end date of 30 December 2026. After that, standard rack rates apply. Bookmarking the official hotel and bank pages is the only way to confirm renewal.

Pros and cons at a glance

Venue Pros Cons
Plate (Carlton City) Lowest effective cost (S$31++ per person); 5 bank partners; explicit weekday/weekend pricing Narrower Hong Kong–themed menu; lunch only on weekdays/Saturday; no dinner 1-for-1 currently published
Café Mosaic (Carlton Hotel) Daily lunch availability; dinner option Thu–Sat; senior 50% off additive Higher rack rate; only 4 bank partners; dinner limited to 4 days

Best for different diner segments

  • Seniors (55+): Both venues offer 50% off. For a single senior, this beats 1-for-1. For two seniors, the per-person cost is identical. Plate’s lower weekday rack rate (S$62++) means a senior pays ~S$31++ alone.
  • Families with children: Plate charges S$28++–S$32++ per child (6–12) and offers free dining for under-6s. Café Mosaic charges a flat S$38 per child (6–12) under the 1-for-1 terms, per the 2024 review. Families with multiple young children will find Plate cheaper.
  • Credit card holders: DBS/POSB, Citibank, OCBC, and UOB cardholders can access both venues. Maybank and Standard Chartered cardholders should target Plate.
  • Budget-conscious diners: Plate weekday lunch 1-for-1 (S$31++ per person) is the cheapest hotel buffet option among the Carlton properties. Café Mosaic lunch (~S$64++ per person) is still competitive against Colony but not the budget leader.

Our pick

For cardholders seeking best value: Plate, Carlton City Hotel – Flavours of Hong Kong weekday lunch. At approximately S$31++ per adult with the 1-for-1, this is the lowest effective per-person cost of any Carlton buffet. The weekday-only limitation is a trade-off, but the price-to-quantity ratio is hard to beat.

For families with children: Same venue—Plate’s child pricing (S$28++–S$32++ for ages 6–12, free under 6) is more favourable than Café Mosaic’s flat S$38 child charge.

For first-time visitors: Café Mosaic at Carlton Hotel offers a daily lunch buffet with a broader schedule, albeit at a higher effective cost (~S$64++ per person with 1-for-1). It’s a safer choice if you are unsure about the Hong Kong theme or want a dinner option.
