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!).
One of the only things I enjoy about taking the subway these days is seeing the defaced ads on the L train. Whether it's random chance, high schoolers or street artists the result is always good.
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.
Its quite a trip out there but so very worth it if you wanna have the very special beach-experience! You can go there by car and then take the ferry either to Pines or Cherry Grove (I would prefer Pines!) or you do all by public transportation - there a "getaway tickes" for 36Dollars and the transfer works really smooth - may even be faster than by car!
