The Offer
This is a short-window dining deal worth acting on quickly. KTC cardmembers can get 30% off at three Bangkok Marriott Marquis Queen's Park connected venues until 30 April 2026: Goji Kitchen + Bar, Sirimahannop at Asiatique The Riverfront, and The Crystal Grill House at Asiatique The Riverfront. The offer is especially useful for readers planning a hotel buffet, a riverside dinner, or a group meal before the month ends.
The headline privilege is simple: 30% off for KTC cardmembers, with no point redemption required. KTC lists the offer as valid from 1 April to 30 April 2026 and limits the privilege to a maximum of 10 persons per card per visit. That makes it practical for couples, small families and work dinners, but anyone booking a larger table should call ahead and confirm how the card limit applies to the group.
What Is Included
Goji Kitchen + Bar is the main buffet angle. KTC states that the 30% discount applies to the international buffet for lunch and dinner, plus beverages. For readers looking for a straightforward hotel buffet deal in Bangkok, this is the most useful part of the promotion because the venue is central, well known, and easier to plan than a one-off event menu.
Sirimahannop and The Crystal Grill House add the riverside angle. Both are listed under the same KTC April super deal, with 30% off food and beverages. These two venues work better for readers who want dinner around Asiatique rather than a classic hotel buffet setting. They also suit travellers staying near the Chao Phraya or locals planning a Bangkok riverside night out.
How To Use It
Book in advance and say clearly that you want to use the KTC dining promotion. The KTC terms say advance seat reservation is required and subject to availability. At the restaurant, pay with an eligible KTC card and check the bill before signing. Because the promotion ends on 30 April 2026, readers should treat availability as limited, especially for dinner seats.
Do not assume the deal applies on public holidays, special events or alongside another restaurant campaign. KTC states that the privilege cannot be used with other promotions, public holidays and special events, and that other hotel conditions may apply. If you are booking for a celebration or a date with a special menu, confirm by phone before going.
Who This Deal Suits
This is best for readers who can dine before the promotion ends and already hold a KTC card. Goji Kitchen + Bar is the safest pick for buffet value. Sirimahannop is more atmospheric for a ship-style riverside evening at Asiatique. The Crystal Grill House is better for steakhouse-style dining where a percentage discount can make a meaningful difference on a higher bill.
Fine Print To Check Before Booking
Because this promotion is only valid through 30 April 2026, readers should not rely on walk-in availability. Call first, ask whether the exact restaurant and meal period are participating on your chosen date, and confirm whether the discount applies before or after service charge and VAT. If you are using the offer for a birthday, corporate meal or group dinner, ask whether the maximum 10-person card limit applies per table, per bill or per cardholder.
The deal is strongest when used for a full meal rather than a light snack. A 30% discount can be meaningful on a buffet, steakhouse dinner or riverside group order, but less useful if you are ordering only one drink. Readers should also compare transport costs: Goji Kitchen + Bar is easier for guests already near Sukhumvit or Phrom Phong, while Sirimahannop and The Crystal Grill House make more sense as part of an Asiatique evening.
