ROAST coffee & eatery
3rd Floor The COMMONS 335 Thong Lo 17 Alley, Khlong Tan Nuea, Watthana, Bangkok 10110
Arrive before eleven on weekends or face a queue stretching to the stairs. The duck hash browns are the single best savoury order on the menu. In-house coffee earns its reputation every time, whether espresso or pour-over. One of the few brunch spots in Thonglor that earns its hype consistently across the full year.
ROAST sits on the third floor of The Commons on Thonglor Soi 17. The market-hall lifestyle centre set a template for Bangkok's indoor-outdoor dining format when it opened in 2016. ROAST has anchored the third floor from the building's earliest days of operation. The cafe's design uses timber and white tile alongside broad windows that pull natural light across the floor throughout the day. The food programme prioritises in-house production at every level. Bakers arrive hours before opening to prepare the daily pastry selection. Chefs cook all proteins from scratch each morning. Baristas work with specialty coffee beans roasted in-house under the ROAST label. The brunch menu draws consistent praise for its duck hash browns, built from confit duck alongside caramelised onion and herb-roasted potato. Banana-stuffed French toast appears in most food photography of the space. Eggs Benedict variations come with a build-your-own component that lets diners choose protein alongside sauce and side options.
Google holds ROAST at 4.5 stars across more than 2,700 reviews, reflecting consistency over years of high weekend traffic. Baristas offer the full espresso menu alongside manual-brew options including V60 and AeroPress. Tables on the outdoor terrace typically fill by 10:30am on Saturdays; arriving before eleven avoids the queue entirely.
The Commons is accessible from BTS Thong Lo via a fifteen-minute walk or a short motorcycle taxi through Thonglor Soi 17. ROAST operates daily from early morning through the late afternoon hours. Weekend mornings see the highest demand across both the indoor seating and the outdoor terrace beneath the rain tree canopy.
