Brewski sits on the 30th floor of the Radisson Blu Plaza on Sukhumvit and has been the city's most-recommended craft-beer rooftop since it opened in 2016. The room runs 24 rotating taps of imported and local craft beer alongside Sukhumvit's full skyline view, a combination almost no other Bangkok bar attempts at this altitude. Time Out Bangkok has flagged it as the city's most-recommended choice for serious drinkers who want a rooftop without paying cocktail prices.
This is the rooftop for the visitor who hates that Bangkok rooftops cost ฿500 a drink and pour mostly tropical cocktails. Pints run ฿280 to ฿380 (about $8 to $11), which is fair for the view and below the going rate for the same beer at street level in Thonglor. Regulars on r/Bangkok consistently flag Brewski as the city's most-recommended rooftop for solo drinkers and small groups who want to settle in.
Hotel guests can take the elevator to 30 direct. Non-guests check in at the lobby first and ride a dedicated lift.
The space divides cleanly. The indoor bar room is air-conditioned, low-lit, and runs the long brushed-metal tap wall along its longest side. The outdoor patio is the better seat: glass railings, full Sukhumvit skyline (Terminal 21 east, MahaNakhon and the Lebua tower south), and enough breeze at 30 floors up that the heat is bearable from October to February. BK Magazine's rooftop review called the patio "the only Bangkok rooftop that feels designed for sitting and drinking rather than posing".

Skip the cocktail list. The kitchen sends out a serious pizza programme (the Bangkok Post's 2024 craft-beer guide called the pepperoni "the city's most-recommended rooftop pizza") and a short menu of Thai snacks. The wings and the Mahanakhon pour are a fair pairing.
The crowd shifts twice a night. Until 9pm the room is mostly expat regulars and visiting craft-beer drinkers who came specifically for the tap list. After 9pm the Radisson Blu's guests filter in for a nightcap and the crowd thins out by 11pm. After 11pm it is the quietest decent rooftop in Bangkok, which is its own argument for a late seat. Per Time Out Bangkok's 2025 rooftop guide, this is the only major Bangkok rooftop where the second half of the night is quieter than the first.
