The best underground shows you will find will have free pbr and models as far as the eye can see. They are rarely announced, so keep your eyes out for promising openings, especially with Milk Underground coming up.

Geek out over the massive menu of Belgian beer at Spuyten Duyvil. Relax in the backyard seating and say, "Ooh, I gotta remember this brew," without realizing you probably won't see it again elsewhere. Then cross the street to Fette Sau, a BBQ experience equally well designed because it's owned by the same couple, the Carrolls. Order from their wide selection of meat cuts, served by the pound on butcher paper. The sides shine too, with the best potato salad and best BBQ beans I've ever had.

Best fried chicken ever, and the speakeasy downstairs is incredible. 

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!

Fun selection of mid century and post modern furniture and design objects.
