FOH stands for Full Of Happiness. The cafe sits on the fifth floor of Nimmanhaemin Soi 5, reached by stairs or a lift that takes three people at a time.
The corner room is glazed floor to ceiling on two sides, looking over tiled rooftops, trees and a church spire to the mountains. Stools line a timber window counter under the glass, and a curved white-topped bar faced in vertical timber slats stands in the middle.
