What to Eat in Bangkok: Thai Flavours

Bo.lan is at 24 Soi Sukhumvit 53 in Watthana. Its cooking is based on traditional Thai food, regional ingredients, biodiversity and produce sourced through local farmers and artisans. Look for southern longkong curry with sea fish and young coconut, smoked duck salad with seasonal Thai fruit, salted crab relish with local vegetables, and stir-fried sam-chun with prawns and squid when they appear on the current menu. Bo.lan publishes a Botanical menu and asks guests to communicate allergies, religious requirements or health concerns in advance; the current menu does not label it vegetarian. Lunch is offered Friday to Sunday; dinner is Thursday to Monday. (Bo.lan, checked 2026-09-29)

R-Haan is at 131 Soi Sukhumvit 53 in Watthana. Its Thai fine-dining format is built around seasonal Samrub menus, a traditional sequence that presents Thai ingredients, indigenous herbs and time-honoured recipes as a complete evening. The official site lists Summer, Rainy and Winter Samrub menus rather than one permanent dish list. Dinner is served daily from 18:00 to 23:00. Reserve ahead, follow the Smart Casual dress code and allow time for the full menu. (R-Haan, checked 2026-09-29)
