JAO.UN is a small cafe selling coffee and tea in the Charoen Chai area of Yaowarat, Bangkok's Chinatown. Its signature drink, TOO DIRTY COFFEE, comes with heavy cream and salted caramel ice cream on top of strong coffee. The shop uses two floors, and lattes, chocolate drinks, and fruit teas are also available. It sits deep in a Chinatown alley, so it is hard to find at first.
