The restaurant is in the plaza area a few steps west from 6th avenue between 46th and 47th street. Reaching this bathroom will take cunning and confidence (and karma) but if you play it right you will be sitting pretty. The bathrooms are on the second floor (where the dining room is) to the right of the top of the staircase. Walk upstairs as if you're there to eat, and if you get questioned by the host you can just say you were down at the bar, which is on the bottom floor. This one gets an accessibility rating of 1 because of the risk factor involved.
