Spire Rooftop Bar Bangkok is a cocktail rooftop bar at the top of the Dusit Thani hotel in Silom, Bangkok. It looks out over Lumphini Park and the surrounding building skyline while serving cocktails and food. Without a reservation, you enter from the Dusit Thani hotel side, queue, and take a different elevator to the rooftop on the 39th floor. Fast pop music plays continuously, so it does not suit anyone looking for a quiet bar.
