The Offer
COPPER Beyond Buffet has a current KTC Mastercard offer that is useful for readers who already know the Pinklao buffet scene or want a clear discount before booking. The deal gives THB 550 off a booking at COPPER Beyond Buffet, The Sense Pinklao branch, when the sales slip reaches at least THB 4,500 and the booking uses the code KTCMASTERCARD. KTC lists the promotion period from 25 March 2026 to 30 September 2026.
This is a booking-led deal, not a walk-in discount to remember at the cashier. The practical route is to reserve through LINE OA @copperbeyondbuffet or Hungry Hub, apply the code before confirming, then pay with an eligible KTC Mastercard. That matters because COPPER is a planned buffet meal for most groups, and the THB 4,500 minimum spend makes the offer best for several diners rather than one casual solo visit.
What It Includes
The published discount is THB 550 per eligible sales slip. KTC says the campaign is limited to one redemption per sales slip and 1,000 redemptions throughout the campaign period. The offer is tied to the COPPER Beyond Buffet The Sense Pinklao branch, so readers should not assume it applies at other buffet brands or branches unless the booking page confirms the same code.
The strongest use case is a birthday meal, family gathering or group dinner where the bill already clears the minimum spend. The saving is meaningful enough to check before booking, but not so large that readers should ignore normal buffet questions such as available time slots, menu tier, child pricing, cancellation rules and whether taxes or service charges are already included.
How To Use It
Book with COPPER through LINE OA @copperbeyondbuffet or through Hungry Hub. Enter the code KTCMASTERCARD during the booking process and check that the discount appears before payment. Bring the KTC Mastercard used for the booking and keep the confirmation handy when arriving at The Sense Pinklao.
KTC says KTC Visa, JCB, UnionPay and KTC PROUD cards are not eligible for this promotion. The cardmember must spend during the stated campaign period, and the discount cannot be treated as cash. If the code is not accepted, do not assume staff can manually add it later; contact the booking channel before confirming.
Before You Book
Check the booking page before you confirm, because the discount only works when the KTCMASTERCARD code is accepted on the reservation. The offer is for COPPER Beyond Buffet at The Sense Pinklao, runs until 30 September 2026, and needs a minimum THB 4,500 spend per eligible sales slip. It is best used for a proper group meal, not a spontaneous walk-in.
