Why start your night at Octave?
Octave Bangkok is where to start your night: the sunset from the 49th floor, a drink in your hand and the whole city lighting up around you. Marriott's own dining page lists Octave and ATTIC by Octave, on the 47th, at the top of the hotel, open every day from 5pm to 2am (checked 4 November 2026).
It's the right start to a night in Thonglor: the view first, then a short ride up the soi to the bars and clubs. Ask Tanner to have the car waiting downstairs when the sun's gone.
What is the Octave dress code?
The Octave rooftop dress code is smart casual, Marriott's own dining page says, and the door checks it. Leave the sportswear, flip-flops and sleeveless tops at the hotel.
Long trousers and closed shoes are the safe call. The drinking age is 20, so bring ID.
This door is strict, so ask Tanner if an outfit is borderline.
- Daily from 5pm to 2am
- Rooftop bar and lounge, Bangkok Marriott Hotel Sukhumvit, Thonglor
- 45 to 49, with the round bar on the open-air 49th
- Smart casual; leave sportswear, flip-flops and sleeveless tops behind
- 5pm, when the doors open, for the sunset
When should you go to Octave?
Be there at 5pm, when the doors open, for the sunset over Sukhumvit.
Weekends fill first, so a group books ahead.
Ask Tanner to check your night and hold a spot at the rail for sunset.
Octave or Sky Bar?
Octave is the 360-degree view and a table. Sky Bar is the Hangover photo over the river.

Doing both? Sky Bar first for the photo, then Octave for the evening. Ask Tanner to time the cars between them.

Where is Octave Bangkok?
Octave Bangkok is at the Bangkok Marriott Hotel Sukhumvit, 2 Sukhumvit Soi 57, a short walk from BTS Thong Lo. In the lobby, ask for Octave Rooftop Lounge Bangkok and the lift takes you up.
After sunset, the Thonglor bars and clubs are a short ride up the soi: see our Thonglor guide. Ask Tanner to have the car at the hotel door.
Which floor should you pick?
Pick the 49th, the open-air top with the round bar and the 360-degree view. That's where you want to be at sunset.
The 45th is the restaurant, with modern Asian tapas for the group before the clubs.
Tanner's pick: the 49th for the sunset, then down to the 45th for tapas, then Thonglor.
Pick your floor when you ask Tanner for the table.
What does a night at Octave look like?
A night at Octave starts at 5pm for the sunset. Then dinner up Thonglor, cocktails on the soi and your own table at a club.
Your cars wait outside. For the rest of the city, see our Bangkok nightlife guide.
Plan it with Tanner.
