If you are referring to the Bua thai, which is located where a fish place used to be. They use curtains for walls and the curtains, either by deisgn or other, leaves a gap just above 5'3 " or so. So that people walking to the other "rooms" can actually see you. I had the owner of the place massage me and half the time she left the room to talk to service people fixing up the place and greeting other customers. It was far from relaxing. In fact i left the place more stressed than when i went in.
Needless to say, there are no extras.
