Gramercy Park Hotel (lobby and roof)

Address: 2 Lexington Ave.

The Gramercy Park Hotel may as well be one of the sickest galleries in New York. But instead of being ushered into a hush-hush space where rich people talk exuberant prices, you can take a seat in either the lobby or roof bar where you can oogle a Warhol, discuss a Basquiat, envy a Damien Hirst, contemplate a Keith Haring, and so on. While the art eye candy is free, the rooftop bar is definitely not—so don't show up with an empty wallet.
