Wolfgang’s Steakhouse Bangkok at One Bangkok has a two-part KTC promotion that can make sense for a celebratory steak dinner, especially when the table is already likely to cross the qualifying spend. The simplest benefit is a complimentary New York-style cheesecake, listed at THB 460++, after spending THB 3,000++ on one sales slip with any KTC credit card.
A second benefit is available to eligible KTC Mastercard holders who register correctly: THB 400 cashback on a THB 5,000 sales slip, or THB 1,000 cashback on a THB 10,000 sales slip. The restaurant promotion page states an overall validity period of 1 October 2026 to 31 August 2027. Because different components carry detailed card rules, confirm the benefit you want before asking for the bill.
How the offer works
For the cheesecake benefit, dine at the One Bangkok branch, pay with a KTC credit card and reach THB 3,000++ on a single sales slip. The complimentary item is one New York-style cheesecake per qualifying slip, subject to availability and the campaign rules. The “++” matters: restaurant prices quoted this way have service charge and VAT added, so check whether your planned order crosses the threshold before those additions or after them at the point of payment.
For cashback, the eligible card must be a KTC Mastercard. A THB 5,000 transaction earns THB 400, while a THB 10,000 transaction earns THB 1,000. These are per-slip thresholds, so splitting a table’s bill can change eligibility. Register once before or on the date of the first qualifying spend, then keep the sales slip until the credit appears.
What to check first
The complimentary cheesecake is not offered on public holidays and festival dates covered by the campaign. The page’s detailed conditions also distinguish between card networks and excluded card products. Tell the restaurant team that you intend to use the KTC privilege before payment, then ask them to confirm that the date and card are eligible.
Cashback is capped at THB 1,000 per card per day and THB 12,000 per card across the campaign. KTC says the cashback can take up to 60 days after the end of the relevant calendar month to reach the account. Spending that earns this cashback does not also earn KTC points under the campaign conditions.
Making the dinner count
This is most useful when your table would naturally order enough food and drinks to reach a threshold. Avoid adding dishes simply to trigger a rebate. A better approach is to decide your preferred cuts, sides and drinks first, estimate the total with service charge and VAT, and treat the benefit as a bonus if the bill qualifies.
Wolfgang’s is at One Bangkok, so allow time for parking or use the direct MRT Lumphini connection. Reserving is sensible for a weekend or business dinner. Mention dietary requirements in advance and ask whether the campaign dessert can be packed if the table is too full to enjoy it after the meal.
Claim checklist
Bring the physical or otherwise accepted eligible card, make the required registration for the Mastercard cashback, and keep the entire qualifying spend on one sales slip. Before payment, confirm the cheesecake, the applicable cashback tier and any excluded dates with staff. If the table is sharing the bill, decide whose registered eligible card will be used before the terminal arrives.
