Sukhumvit 39 in Thonglor hosts Cul de Sac on the 10th floor of Quartier by Montraj, an upscale rooftop bar serving cocktails.

#10 of 32 rooftop bars in Thonglor+0.2 vs the Thonglor average of 4.7

## What reviewers say

Inventive cocktails and standout dishes—particularly the Barrio Beef Tacos and Sunset Bocconcini—draw consistent praise, accompanied by attentive service from staff who go above and beyond. The 'rooftop' designation misleads: enclosed by plants on a third floor, the bar offers no skyline views, denies pool access despite having one on-site, and charges above-market prices for limited menu variety.

- Barrio Beef Tacos and Bocconcini
- Inventive, unique cocktails
- Attentive, personable staff

- Enclosed by plants—no skyline views
- Prices above comparable venues
