Radisson Hotel Chateau de Bangkok is offering KTC cardholders 15% off eligible food and beverage from 1 August to 30 December 2026. The benefit is designed for a normal hotel dining bill rather than an open-ended stack of vouchers: a reservation is recommended, the table limit is ten cardholders or guests per visit, and blackout dates can apply around public holidays and festival periods.
The cleanest way to use it is to call the hotel before travelling, name the KTC promotion and ask which outlet, menu and meal period qualify for the date you want. That short check also lets you confirm whether a buffet, set menu, alcohol, room service or special event is treated differently. Pay with the eligible card and review the itemised bill before leaving.
Check The Calendar
The published campaign window runs until 30 December, but that does not mean every day inside it is eligible. Public holidays, festival periods and hotel-led special events may be excluded. In December, festive menus can replace the standard à la carte offer well before New Year’s Eve. Ask the reservations team to confirm the exact date, meal and outlet in writing when possible. If your visit is for a birthday or business meal, mention that too: deposits and private-room packages may follow their own terms.
Reserve Before Travelling
The offer is subject to availability, so a table is not guaranteed simply because the promotion is live. Call 02 116 2222 and state that you intend to pay with KTC. Confirm the reservation name, party size, time and outlet. A same-day reconfirmation is sensible for a large group. If staff quote a different benefit, ask them to identify the live campaign attached to your booking rather than arguing from a saved social post or an old hotel brochure.
Know The Table Limit
The promotion permits a maximum of ten people per eligible card per visit. A larger party should ask the hotel how it will be seated and billed; do not assume two cards automatically create two qualifying tables. The 15% saving is most useful when the whole table orders from an eligible menu. If one guest chooses a special package or event menu, the hotel may need to separate that item from the promotional subtotal.
Read The Bill
Ask whether the percentage is applied before service charge and VAT, then compare the printed subtotal with the menu prices. The final saving will not always equal 15% of the amount charged to the card if taxes, service, excluded drinks or packages sit outside the calculation. Resolve a missing benefit before payment. Keep the receipt until the transaction posts, especially if a deposit was taken earlier or the table changed its order during the meal.
Avoid Stacking Assumptions
The KTC benefit cannot be combined with another promotion. Hotel membership rates, birthday vouchers, dining credits and third-party booking coupons may therefore be alternatives rather than additions. Ask for both net totals if another offer is available, then choose the route that actually costs less. A nominally larger percentage can lose to a fixed-value package that includes beverages or a course your table would otherwise order separately.
Make The Meal Worthwhile
A deal should support the meal you wanted, not encourage unnecessary spending. Review the current menu, dietary options and last-order time before booking. Tell the restaurant about serious allergies directly; a card promotion does not change kitchen cross-contact risk. For a group, agree whether the bill will be shared before ordering. The discount is easier to use when one person pays the eligible bill and companions settle among themselves afterwards.
