The New York Post dispatches its own Post Potty Patrol to report on the best bathrooms at restaurants and clubs in the city. The bathrooms they choose? The ones at XL, bar 89, Tao (we were familiar with the pachinko machines in the ladies' room, apparently the men's room is the place to be), Jekyll & Hyde, Dusk, Noa, and Glass, plus the ones at Jay-Z's 40/40 . Gothamist is very familiar with various bathrooms in the city, we'd like to add that the bathrooms at Brasserie are cool, with that orange resin trough/sink. And at the shared trough sink (must be a brasserie thing) at Pastis, we washed hands next to Jean-Georges.
If you're in Hong Kong, the most decadent bathrooms in the world might be at the nouveau cuisine restaurant Felix, which is atop of the swank Peninsula Hotel.
Designed by Philippe Starck, the bathrooms have floor-to-ceiling windows overlooking the city; the men's urinals overlook the city, letting Masters of the Universes essentially pee onto city while ladies can only primp at vanities by the windows.
