You can't say you've seen NYC until you've seen it from a boat. Hop on the ferry from anywhere to anywhere and you'll see what I mean. Not only will you see excellent old buildings and factories--the inner workings of the old industrial city--but you'll head out under working bridges and see the skyscrapers in all their towering glory. And once you've done it, do it again, at night.
This is a great park, from free concerts to summer to the Brooklyn flea markets over the weekend or take the ferry across the river. Rain or shine I never get sick of that view.
Best contemporary art museum in NY, have to take a train that goes along the Hudson river (best views during fall season!) / rent a car. This museum only uses natural light, and has pieces from Richard Serra, Judd, Sol Lewitt, Walter de Maria, Robert Smithson, Flavin, all best of the best!
This is the place where I ate my first burger just 2 hours after I arrived in 'tha hood' I loved the place immediately because of the supersweet employees. And the fact that they have al this vintage machines in the place: like an old COKE machine and a cigarette machine as well as a jukebox from the sixties. The fact that they serve ALL DAY LONG BREAKFAST really made me happy, probably because I lived in Berlin before I moved here and there people are endlessly chilling and having breakfast the whole day long anyway! On wednesdays Wally organizes film evenings with funny nineties classics and on thursday evening you can eat a 5 dollar burger menu. While eating your inexpensive burger think of Wall.E.
