Flashback Rooftop Bar

What is it: Flashback sits on the 9/F of the Tastoria Collection Sukhumvit on Soi 20, with views of the BTS Skytrain viaduct and Sukhumvit mid-rise skyline from a sociable rooftop with a pool. The retro-neon aesthetic, ’90s music references and rotating monthly cocktails give it a distinct personality. Live bands perform regularly and the Thai-Western menu – including a northern sausage spaghetti that has developed something of a cult following – keeps guests well fed throughout the evening.

Why we love it: In a city where rooftop bars default to marble and dress codes, Flashback is refreshingly without pretension. Happy hour BOGO deals until 7pm, a pool, live music and a proper kitchen – rarely found combined at a single Bangkok rooftop. The vibe shifts naturally from casual sunset drinks into a livelier late-night scene.

Time Out tip: Happy hour runs until 7pm – arrive by 5pm to secure a table with a view before the pool crowd fills in. Handles group bookings and birthday parties well; contact in advance for large groups.
