An interesting dining experience. They put in a cute show with all the liquid nitrogen and foams, but at the end of the day, they make a good meal. I really enjoyed my lamb shank main plate. My wife really liked her smoked duck. However the oysters were a disappointment, not much there.
As others have said, it's 3 floors up a narrow flight of stairs (definitely not handicap accessible). If you have more than a few drinks, it would probably be sketchy going back down.
