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.

If you're far up in Greenpoint and need caffeine + snack, Bakeri is my spot (I say "bake-ery", others say "bach-ery"—I still vote the former). Known for their baked goods—both savory and sweet—it's the perfect spot for a coffee meeting, small breakfast, or a solo book read. There's one large communal table in the center, plus a few two-tops and decent counter space—one of the rare cafes with enough room that it's rarely packed (except saturday!). 

My favorite Chinese food spot. The best Peking duck! Ignore the C health code rating in the window, they must have made a mistake ;) Also, It's BYOB with no uncorking fee, go crazy.

Everybody loves pizza, and Roberta's is hands down the best Pizza's in New York. I love going here on the weekends, visit MoMa PS1, go watch graffiti - studio visits as long as it ends or starts with a Pizza 

The permanent piece called "Meeting" at MoMA PS1 is an etherial experience of light and color and quiet. Sit and look through the cutout in the ceiling and watch the light change both outside and in. You can't tell what you're looking at until maybe a bird flies by.
