Pier 21 is a food court on the fifth floor of Terminal 21 next to Asok station in Bangkok, selling Thai food, desserts and drinks. The menu includes pad thai, oyster omelette, chicken noodles, mango sticky rice and thangmo pan, and the space is air-conditioned. At the counter near the entrance, cash is loaded onto a dedicated card, and each stall is paid by scanning the QR code on the back of the card; the remaining balance is refunded when the card is returned. During meal times it is crowded and hard to find an empty seat.
