Public Hotel
If you're partying at Public Arts, there's almost always a bathroom attendant watching you like a hawk. But we'll tell you a secret: the downstairs bathrooms in the lobby are usually empty, and they're somewhat unisex (men's and women's stalls are separated but you can easily slip in). Plus, each stall is like a room, with very heavy doors - no one will hear you!
