Cooling Tower, Rooftop Bar is a rooftop bar on the 34th floor of the Carlton Hotel Bangkok Sukhumvit in Watthana, Bangkok, serving cocktails and whiskey. It pairs its drinks with music and cool breezes. Staff take whiskey orders on the rocks without issue and greet guests who come with their parents warmly. The surrounding scenery is not flashy, so the view falls short even from the high floor.
