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.

When I first visited NY in 2010 the New Museum left a permanent impression. I love the architecture and the concept of the piled-white-shoe-box look-a-like building at the edge of the Lower East Side neighborhood. The exhibition program is appealingly different, and the bookstore in the foyer is not to be missed!

Part of the Marlow restaurant group, Diner is one of the more casual / rustic options. The menu changes daily and is written out (most likely upside down by the wait staff) on your table or the back of a receipt. The only constant item is the burger, which to be honest, is one of the best in the neighborhood. If they have a breakfast sandwich for brunch, get that. The fried chicken sandwich (with dark meat) is also a favorite. They make scrambled egg dishes better than most. Dinner is solid all around (they crush a steak for two). Homemade ketchup and dijon mustard are on every table, so regardless of what you get, these two condiments are worth the visit. 

A new-ish cinema located in the East Broadway section of Chinatown. They play a great selection of rare and vintage titles, plus hosting a considerable amount of director/cast Q&As post showing. People complain about their seats, but they're really not that bad. And yes, they have overpriced fancy snacks, but what theater has cheap snacks?! Go to Mission Chinese, Dimes, or Fat Raddish for dinner—all options around the corner. 

Coming back from from New Haven, we got off at Grand Central and he took me down one of the concourses to the place with the vaulted ceiling. He stood at one corner and I stood at another and we whispered into the walls, our voices drifting across to each other.
