1-for-1 Weekday Lunch Buffet & Seafood Buffet Deals in Singapore: 3 Live in September 2026, Crab & Lobster Back 10 Sep, From ~$31++/pax

The most accessible deal on this list: Café Mosaic on Level 1 of Carlton Hotel runs a 1-for-1 Hong Kong Kitchen lunch buffet at $62++ per person from Monday to Friday, so with the second cover free it is about $31++ a head. Since 31 August 2026 the weekend rate has been split out: Saturdays, Sundays and public holidays are $68++, or about $34++ each. It's open to DBS/POSB, Citi, OCBC or UOB cardmembers (one of the widest card nets around), daily from 12pm to 2.30pm. Expect a dim-sum-forward spread with roast meats, congee, noodles and a dessert line in a comfortable town-area hotel setting near Bras Basah / City Hall. Often missed: the same 1-for-1 also applies to the Hong Kong Seafood Dinner Buffet, Thursday to Saturday evenings (6–10pm, last order 9.30pm) at $138++ per adult since the same 31 August change, so about $69++ a head for a bigger spread with premium seafood, roasted suckling pig and Hong Kong desserts. That makes Café Mosaic the one entry here that covers both a 1-for-1 lunch buffet and a 1-for-1 seafood dinner buffet on the same four cards. Two things worth knowing. The hotel has still not announced an end date for this 1-for-1, and we re-read its rate card on 1 September 2026: the increase it had flagged has landed, but only in part. Weekday lunch held at $62++, so the headline ~$31++ survives from Monday to Friday; it is the weekend and public-holiday lunch that went to $68++ (~$34++ each) and dinner to $138++ (~$69++ each). The 1-for-1 is dine-in only and doesn't apply on public holidays, their eves or special occasions, and seniors 55+ can take 50% off instead (not stackable with the card deal). Children aged 7–12 are $18 at lunch and $38 at dinner. BEST FOR: a cheap, central lunch buffet where almost any major card gets you in, or a half-price hotel seafood dinner from Thursday to Saturday.

The best halal buffet value here, and the one deal on this list with no deadline: Permata, set in the heritage yellow mansion (Gedung Kuning) at 73 Sultan Gate, Kampong Glam, runs a 1-for-1 halal buffet at $88++ for two at lunch and $108++ for two at dinner, so $44++ per adult at lunch or $54++ at dinner. Permata's own booking system estimates the all-in bill at $105.50 nett for two at lunch and $129.50 nett for two at dinner, which is the number to plan around once GST and service charge land. The spread runs 50+ local dishes and rotates by showcase: Permata's own site currently lists two, The Lion City and Flavours of the East Coast, so the menu you get depends on which is running when you book. Expect a Warisan Singapura Nasi Lemak station, Singapore chicken rice and the Peranakan classic Ayam Buah Keluak. Daily 12–2.30pm and 6–9.30pm. CORRECTION TO WHAT WE PUBLISHED IN JULY: this is not an SG61 National Day promotion and it does not stop on 31 August. The 1-for-1 is Permata's standing booking format, its reservation page lists the sittings as "1-For-1 Lunch Buffet" and "1-For-1 Dinner Buffet", and we re-opened that booking page on 1 September 2026 and found both sittings still bookable, with every price unchanged and no end date published. You claim it by booking that sitting, not by quoting a promo code at the table as we previously wrote. Worth knowing before you book: children under 7 eat free, 7–12s pay $20++ at lunch and $24++ at dinner, 13–17s pay $28++/$34++, and seniors aged 60 and above pay $38++/$44++, less than the adult 1-for-1 rate, so an older couple should book as seniors rather than as a pair. There is a modest dress code (no shorts, singlets or slippers) and a $15 nett per-person charge for no-shows or cancellations inside 24 hours. BEST FOR: a halal, local-flavoured buffet in a beautiful heritage setting, the cheapest halal option here, and the only deal on this list you can still book in October.

A relaxed afternoon spread at half price for two: Hari's Lobby Lounge & Bar at Holiday Inn Singapore Orchard City Centre runs a 1-for-1 Straits Indulgence high-tea buffet priced at $78++ for two (minimum two diners), so about $39++ a head, with each additional guest at $42++. It's a Peranakan-leaning afternoon-tea buffet with local kueh, savouries and sweets, the savoury end runs to lobster and chilli crab meat in brioche and a sambal baby abalone nasi lemak tartlet, served daily from 12pm to 5pm. No particular card is needed, so anyone can book it, which makes it one of the easiest deals here to actually use. DATE CORRECTION: we had this ending on 31 August. The hotel's own dining offers page dates the run 16 June to 4 SEPTEMBER 2026, which we re-read on 1 September, so it has a few days left rather than none. One catch buried in the terms: the 1-for-1 cannot be combined with other discounts, loyalty points or special offers, so the up-to-20% IHG Rewards dining privilege does not apply on top of it. BEST FOR: a leisurely high tea with a friend or your mum on Cavenagh Road, without the à la carte hotel-tea price.

ADDED ON OUR 20 AUGUST RE-CHECK, and it answers the question this guide gets asked most. Holiday Inn Singapore Orchard City Centre runs a Crab & Lobster Dinner Buffet on a 1-for-1 basis, Thursday to Sunday, 6–10pm, which ran till 30 August 2026. The published rate was $158++ per adult with the 1-for-1 applied, $40++ per child aged 6–12, and children under 6 eat free for up to three children per paying adult. WHAT YOU GET: lobster is free-flow across three stations, chilled garlic-marinated baby lobster at the seafood bar, grilled lobster and grilled scampi rotating through the BBQ live station, while the Wok Hey station rotates Singapore chilli crab with mantou, black pepper crab, salted egg crab, kam hiong crab and Nyonya curry crab. Around them sit fresh oysters, grilled abalone, scallops on the shell, live cooked prawns, gong gong, golden clams and blue mussels, plus a sashimi and sushi counter, a crab briyani and crab masala section, and a laksa/prawn-and-crab-meat noodle station. NO CARD NEEDED, which is rare at this level, and a free IHG One Rewards membership takes a further 10% off, though only on direct bookings, and the offer cannot be stacked with other discounts or loyalty points. THIS RUN HAS ENDED, AND THE SUCCESSOR IS DATED. The Orchid Ballroom edition closed on 30 August 2026 as scheduled, and the hotel has already posted its replacement: CRACK, DIP AND INDULGE, THE CRAB & LOBSTER BUFFET DINNER, 10 SEPTEMBER TO 22 NOVEMBER 2026, back at Window on the Park on Level 2 now that its renovation is finished, still Thursday to Sunday 6pm to 10pm and still 1-for-1. Two things moved. The price is now S$168++ FOR TWO ADULTS, about $84++ each, against the $158++ we recorded, and the hotel finally states it unambiguously as a two-adult figure, which settles the per-adult-versus-per-pair wording we flagged as unresolved. Children 6 to 12 stay at $40++ and under-6s still eat free, up to three per paying adult. New in the September terms: groups of six or more get a complimentary bottle of house red or white, swappable for soft drinks by the glass for the whole table. Direct bookings only, IHG One Rewards members still take a further 10% off the 1-for-1, prices exclude 9% GST and 10% service charge, and there is a ten-day gap with no buffet between 31 August and 9 September. The same reopening brings an INTERNATIONAL WEEKDAY LUNCH BUFFET at Window on the Park from 7 September to 22 November 2026. BEST FOR: the 1-for-1 seafood buffet this list previously could not offer, free-flow lobster and five styles of crab, with no particular bank's card required.

THE BIGGEST CHANGE ON THIS LIST, AND IT IS NOT A PRICE. Carnivore Brazilian Churrascaria is closing for good at the end of September 2026, after 20 years, at its Robertson Quay outlet. Its DBS/POSB 1-for-1 all-you-can-eat buffet at a usual $89++ (about $44.50++ a head) had already ended on 31 July, but the restaurant has replaced it with farewell pricing that is worth more than the 1-for-1 was to most people. It's the classic churrasco format: passadores bring rounds of fire-roasted meat (picanha, beef, lamb, chicken and sausages) carved straight onto your plate, alongside a sides and salad spread. While the deal ran you paid with a DBS/POSB card (POSB Everyday Card also earns up to 10% cash rebates), dine-in only, 90 minutes per seating, advance reservation required, one card covering up to 4 diners (2 paying). WHAT IS ON NOW: reading Carnivore's own promotions page on 1 September 2026, the headline is Obrigado Singapura, its finale season, which prices the buffet at $50++ per person Monday to Thursday and $60++ Friday to Sunday, with no credit card required. Whether that beats the old deal depends on who you are. Two people sharing the old 1-for-1 paid about $44.50++ each, so a pair is now slightly worse off on a weekday. A solo diner is far better off, paying $50++ instead of the $89++ a single cover used to cost, because a 1-for-1 was never any use to one person. Read the exclusions before you book: the farewell price is not available from 5 to 7 September, which the restaurant blocks out for Brazil's Independence Day, seatings are 90 minutes, and it cannot be combined with other promotions, vouchers or privileges. The SAFRA and 11B offer that ran alongside it has expired with August. Also still on the page: a year-round 15% off the adult dinner buffet for flight crew with a valid crew pass (excluding public holidays and special occasions), and all-day happy-hour drink pricing for dine-in buffet guests, Dester draft at $6.90++ a pint (top up $1++ for an extra half-pint) or $38++ a tower, a Cass bucket of four bottles at $20++, and cocktails from $6.90++ (the shandy; the rest are $10++). Children under 0.9m tall dine free. Reservations are by WhatsApp (+65 6334 9332) or email rather than an online form, and a closing restaurant fills up, so book early. BEST FOR: serious meat-eaters and groups who want one last go at eating their money's worth of grilled protein before the doors shut.

A premium Orchard Road lunch at half price: Crossroads Buffet at Singapore Marriott Tang Plaza runs a DBS/POSB 1-for-1 weekday lunch buffet at a current listed price of $72++ per person, so about $36++ a head with the second cover free. The spread leans international-plus-local, with fresh seafood on ice, a Chinese barbecue section, a make-your-own kueh pah tee station and a live mala stir-fry pot. It's a weekday lunch deal (12–2.30pm), right at the Orchard/Scotts junction. HEADS-UP: the 1-for-1 ends on 31 July 2026, and Crossroads' own promotions page does not list a replacement 1-for-1 after that. What it does list is a 20% discount on the adult price, quote the code CR20OFF when you reserve, running from 6 July to 30 September 2026 across the buffet's current menus, weekday lunch $72++, Saturday lunch $84++, Sunday–Thursday dinner $92++, Friday–Saturday lobster dinner $120++ and the Sunday Champagne Brunch at $99++, with the child price a flat $42++ on every one of them. The exception to check: the $146++ version of the Sunday brunch, which adds free-flow champagne, draught beer and house wine, is explicitly excluded from the discount. It is not as good as 1-for-1, but it needs no particular card, and it is the offer still standing: we re-read the Crossroads promotions page on 1 September 2026 and CR20OFF is live, unchanged, to 30 September. Not valid on the eve of or on public holidays and special occasions. BEST FOR: a treat-yourself weekday lunch in town, half price with DBS/POSB until 31 July, then 20% off with CR20OFF through September.

A hotel dinner buffet at half price for two, but check the venue before you go. The Westin Singapore runs a 1-for-1 semi-buffet dinner at a usual $98++ per adult, so about $49++ a head with the free second cover ($40++ per child aged 4–12). IMPORTANT: the Seasonal Tastes restaurant is closed for a refurbishment from 18 May to 31 August 2026, and the buffet is running as the 'Seasonal Tastes Pop-Up' at Cook & Brew in the same hotel, so don't head to the usual Seasonal Tastes floor. 'Semi-buffet' means you pick a main course and the rest is buffet, with free-flow soft drinks, coffee and tea; menu items rotate and are subject to change. It runs Mondays to Fridays, 6–10.30pm, with the 1-for-1 applied when you pay with a participating bank card (Citi, DBS/POSB, OCBC and UOB among them), excluded on public holidays and their eves. On weekends and public holidays it becomes a full buffet at $108++, also 1-for-1 (so ~$54++/pax). ONE THING TO GET RIGHT: only the pop-up's DINNER sittings are 1-for-1. The pop-up lunch, $48++ on weekdays, $58++ on weekends and public holidays, is a different, weaker offer: the second diner gets 50% off, not a free cover. So come for dinner if you want the 1-for-1. The hotel also flags occasional renovation noise while the works are on. Two practical notes: children aged 3 and under eat free, and since 1 July 2026 every venue in The Westin is fully cashless, credit or debit cards only, so bring the card the promo needs and nothing else. AFTER THE REFURBISHMENT: the restaurant has now published what comes next, Seasonal Tastes reopens with reservations from 1 September 2026, with a Lunchtastic Buffet at $68++ per adult Mondays to Thursdays and $78++ Fridays to Sundays ($34++ per child aged 4–12), and a Seafood Dinner Buffet at $128++ per adult ($55++ per child). Importantly, the offer changes shape: instead of 1-for-1, the second diner gets 50% off when you pay with a DBS/POSB, OCBC, UOB, JCB, Maybank, B.O.C, Amex or Citibank card, adults only, buffet only, advance reservation required, maximum 10 pax per reservation, and not valid on the eve of or on public holidays. So the 1-for-1 window here genuinely closes on 31 August 2026. BEST FOR: a proper sit-down hotel dinner buffet for a birthday or date, without the full $98++ hit, and worth booking before the offer softens in September.

ENDED: TungLok Seafood's Citi 1-for-1 deluxe à la carte buffet at Park Regis by Prince Singapore (near Clarke Quay), usual $59.80++ per adult, about $30++ each with the free second cover, finished on 31 July 2026. The SG61 Deep-Sea Golden Croaker at 61% off, which we listed here as the consolation prize, has gone too: TungLok's own copy ended it on 30 August 2026. Re-reading the promotions page on 1 September, there is now no buffet offer and no bank-card offer of any kind. WHAT'S ON INSTEAD, none of it a buffet: TungLokFirst members get 50% off a selected signature dish daily, dine-in only, till 30 September 2026; Dancing Crab has weekday lunch sets from $19++ with the second set at half price; Dancing Crab happy hour runs bottled beers and cocktails from $7 with 50% off selected bar snacks till 31 October 2026; a $200 spend at Dancing Crab earns a free #2 Combo Bag worth $60++; and Mid-Autumn mooncakes are on till 25 September 2026. The restaurant is still worth knowing for order-to-table Chinese seafood cooked fresh rather than sitting under heat lamps. BEST FOR: seafood lovers who'd rather have dishes cooked fresh than queue at a buffet counter.
