I don't know what I was expecting from Kushi but after a lot of hype, I guess I was expecting more from the whole experience. As for the restroom, the two unisex single stalls were understated and subdued. Bathed in black with white porcelain accents, the streamlined room had some extra touches with a flower/plant. The most interesting part of the bathroom for me was the hot and cold handle which moved vertically as opposed to right and left to turn on the water.

What you don't see in this picture is the urinal across from the toilet. Not being male, I see those types of things in a unisex stall as unnecessary, but I'm sure others would beg to differ. Also not pictured, the free standing toilet paper roll holder, which often strikes me in a place that's trying to be informal as they didn't have time to put a holder on the wall.
