Siam Tea Room (Bangkok Marriott Marquis Queen’s Park)

Known for heritage flavors done with hotel polish, Siam Tea Room usually brings back its Khao Chae as the mercury climbs. Look for cleanly scented chilled rice and a full board of traditional sides, from preserved radish stir-fry to shrimp paste balls with just the right funk, plus carved vegetables for crunch. The setting is comfortable and air-conditioned, perfect for lingering over the ritual of alternating cool rice with savory-sweet bites. Portions are balanced for a light lunch or shared snack. Pre-orders and daily limits apply, so call ahead if Khao Chae is your main reason for visiting. Takeaway is straightforward if you’re picnicking at Benjasiri Park nearby.
