On Top Rooftop Bar is a bar in the Bang Rak area of Bangkok that serves food and cocktails, with views of the Chao Phraya River and a BTS station. Guests pass through the indoor bar and go up one more level to the rooftop, where they look out over the river and the Bangkok night skyline. To get there, ask first at the corner restaurant on the ground floor, then take the stairs up to the 5th floor; the rooftop is above that. The climb up several flights of stairs to the rooftop is a drawback.
