Octave Rooftop Lounge & Bar อ็อกเทฟ รูฟท็อป ลาวจ์ แอนด์ บาร์

Octave takes floors 45 to 49 of the Bangkok Marriott Hotel Sukhumvit at 2 Sukhumvit Soi 57, two or three minutes on foot from BTS Thong Lo exit 3. Enter through the hotel lobby and take the dedicated lift. The 45th floor is the restaurant, the floor above is a bar, and the top floor is the open-air circular bar with the 360-degree view that most photos show. Wandering Asia's 2026 review lists signature cocktails at 410 to 450 baht, classics at 370 to 450, a mojito at 370, Singha or Heineken at 250 and sushi at 270 to 340 a piece. The same review reports a minimum spend of 1,000 baht per person for a table; standing at the bar or railing has no minimum and there is no cover charge. Happy hour runs 17:00 to 19:00 with 50 percent off selected drinks. Most Wongnai members report spending over 1,000 baht a head and recommend the sweet potato fries, torched salmon, prawn sliders and grilled river prawn; Time Out notes cocktails built on Thai ingredients, such as a Thai mojito with Thai rum, mango and basil. Dress code is smart casual: no sportswear, flip-flops or sleeveless tops for men. It opens at 17:00 daily; sources give closing times between 01:00 and 02:00, with a DJ from about 20:00. thonglor.in.th suggests arriving an hour before sunset for a railing spot, and Wongnai reviewers warn that the top floor is windy and that the covered zone is often booked out when it rains.
