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!).
This place is very good. Korean inspired diner food. Get the Breakfast Burrito with Sausage, Honey Butter Pancakes, Chicken Katsu. The mushroom burger is very good too.
Mcgolrick Park at midnight in the snow. Any early morning with all the bums and drunks passed out on Nassau Avenue. NYC still looks best between 3am and 6am, just before the light comes in to shine on all its flaws.
