This artist-run gallery is a hub of the Brooklyn gallery scene. You'll find Bungee, a celebrated fixture, snoozing comfortably in the office and somehow oblivious to all the surrounding chaos.
Beach approachable by public transportation and can be connected with a visit of MOMA PS1 Art Installation (Katharina Grosse House) Also less crowed than other beaches in NYC.
You've heard about the reading room at the New York Public Library, haven't you? Then I need not go on. Just look at it. And you're allowed to hang around in there!
