COCA, the Thai-Chinese hotpot house that opened in Bangkok in 1957 and landed in Singapore in 1987, put a promotion on its official Facebook page on Wednesday 9 September 2026 that its own promotions page does not carry: $99 off the Signature Dinner Buffet with every 4 paying adults, Mondays to Thursdays only, 9 to 30 September 2026.
> Quick view: $99 off per 4 paying adults · Signature Dinner Buffet only · Mon to Thu, 9 to 30 Sep 2026 · COCA Suntec City #02-440, the only outlet · about $32.67 nett a head against $62.35 · payment by COCA Wallet only · no stacking with member or senior rates.
What four people actually pay
COCA's weekday Signature Dinner Buffet is $52++ an adult. Four adults is $208 before charges, and $249.39 nett once the 10% service charge and 9% GST are added, which is $62.35 a head.
The $99 comes off the subtotal before those two charges. That leaves $109, which grosses up to $130.69 nett, or $32.67 a head. COCA's own caption puts it at "around $33 NETT per pax", which is how you can tell the discount is applied pre-charges rather than at the bottom of the bill.
The number worth remembering is not $99. Because the service charge and GST come off along with the discount, the bill drops by $118.70.
| Four adults, weekday dinner | Subtotal | Nett | Per head |
|---|---|---|---|
| Normal price ($52++ each) | $208.00 | $249.39 | $62.35 |
| With $99 off | $109.00 | $130.69 | $32.67 |
| Gold member, 20% off | $166.40 | $199.51 | $49.88 |
| Platinum member, 25% off | $156.00 | $187.04 | $46.76 |
| Diamond member, 30% off | $145.60 | $174.57 | $43.64 |
| Four seniors at $44++ each | $176.00 | $211.02 | $52.76 |
The two conditions that decide it
- Payment must go through the COCA Wallet. Signing up for COCA Membership+ is free, but the wallet is prepaid: you top money in before you eat. That is real cash parked with a single-outlet restaurant, so top up what the meal needs rather than what unlocks a tier.
- No stacking. The post says the promotion is not valid in conjunction with other promotions, discounts, vouchers or privileges. That rules out the wallet's own member rate (20% Gold, 25% Platinum after $1,500 of top-ups, 30% Diamond after $5,000) and the separate $44++ Senior Citizen dinner rate for diners 60 and above.
You are not giving anything up. At a table of four the $99 beats every one of those, including the 30% Diamond rate that takes $5,000 of cumulative top-ups to reach.
The rest of the fine print
- Minimum 4 paying adults. Children are not paying adults: COCA charges $18++ for ages 7 to 11 and lets under-7s eat free, so two adults and two children does not qualify.
- Signature Dinner Buffet only. Not the lunch buffet, not the Weekday Set Lunch, not the Premium Seafood Buffet, not a la carte.
- Mondays to Thursdays in September 2026 only. Friday, Saturday and Sunday are out, and the weekend adult buffet is $56++ ($67.14 nett) in any case.
- COCA's post ends with "other terms and conditions apply", so treat anything not written above as unsettled.
Nights you can actually use it
Thirteen are left: 9, 10, 14, 15, 16, 17, 21, 22, 23, 24, 28, 29 and 30 September. There is no public holiday in that stretch, and 30 September falls on a Wednesday, so the last night of the promotion is also a qualifying one.
Dinner service at COCA Hotpot, 3 Temasek Boulevard #02-440 Suntec City runs 5pm to 10.30pm Monday to Friday, with last order at 9.45pm. It is the brand's only outlet, so there is no participating-outlet list to check. There is one private room, seating 10 to 12.
One thing to watch
This promotion is not on coca.com.sg. We read the promotions page on 9 September and it lists only the Quick COCAlicious Set Lunch and the Birthday Month Promo. The Facebook post is the only official surface for the $99, so screenshot it before you go, and confirm the terms when you reserve.
