The view is the headline, but the four-floor layout is what keeps it comfortable. Lower floors lean lounge, upper floors lean sky. Lead with the Thai fusion tapas, then move to the sushi and shareable boxes if the group is hungry.

You step off the elevator on the 45th floor and the city opens in every direction. Bangkok Marriott Hotel Sukhumvit sits above Thonglor, and Octave uses all of that altitude across four stacked levels. Each floor reads differently: more seats, more shade, or more sky depending on where you settle. The top delivers the clearest 360-degree sweep.

The kitchen runs Thai fusion tapas with a modern edge. Sushi, sashimi, and shareable boxes (hot or cold) anchor the menu around 1,550 baht. Asian-style tapas platters and a seafood bar fill the rest of the card, and the wine and cocktail list matches the altitude. Resident DJs hold the room every night of the week, so the vibe tilts lounge rather than quiet rooftop.

The venue opens at 5PM and runs until 2AM daily. That makes this an evening-and-night play, not a lunch or daytime stop. Seating is plentiful across the four floors, so you are not competing for a table the way some Bangkok rooftops force you to. The space was built with room to move, and it shows. Live music and quiz nights surface in the weekly rotation, pulling in groups and solo diners equally.

If you want the uninterrupted panorama, aim for the upper floors where the sightlines clear. Lower levels still deliver the view but trade some of that openness for more shelter and seating variety. The 49th floor holds the circular bar and the DJ booth, so that is where the energy concentrates after dark. Reservations go through the hotel and online via SevenRooms.
