Moma is worth a visit, but for a more lively Art experience ánd for free, one should visit Chelsea. A colony of 400 Art Galleries, showing the best in contemporary art. Running straight through is the high line, a 1 mile long linear park, build on a former railroad-spur, worth the walk.

Prospect Park is a great place to have a water balloon fight, a picnic, a jog, and play with other people's dogs.

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!). 

Going for a stroll on Atlantic Beach is a fall Sunday must. I rarely go to the New York beaches in summer because of the crowds, but standing on an empty, windy beach is a total mind soother. Make sure to take a peek at the Miami-colored Catalina Beach Club. Beaches close mid-September.

Warm winter holiday vibes all year long, especially during the holidays. A hint of the old NYC where one could be a functioning alcoholic by day and artist by night. Proper characters here, the lore is deep.
