By 1 a.m., it seems as if the entire Warehouse District is inside Bar Flyy. Once you work your way past the inevitable line, the Flyy offers two levels of loud, crowded, sweaty fun. The upstairs boasts two bars and a dance floor, but the real party is downstairs. Dark enough to make everyone look pretty, an area of plush couches offers a space where you can get to know your new friend. And the dance floor is big enough to house plenty of hotties, but small enough to pack them in nice and tight. If you go home alone, that's your call.
