This is a pro tip, but also a summer tip, take the ferry from Lower Manhattan to Rockaway and spent the day. The beach is great and the area is impossible to gasp that it's 30 min from Manhattan (without traffic) - Eat as many tacos you can, cause it's the best in the state of New York!
Chinatown in general, I've lived in chinatown on and off for my entire time in New York and i never tire of it’s textures, smells, artificial lighting and grime. There's some amazing things to happen upon there as you trek about your way, a true city experience. Love this little culture shop Aeon, gems of records, art and ephemera tucked away like most good things are.
The reputation of Mission Chinese Food is for being cool, weird, and extremely eccentric, which tends to mean that you either love it or hate it (an assessment that is at least somewhat correlated to your personal tolerance for spice).
I love sneaking over here in the middle of the day to see a movie - they always have the best selection of films. I recently saw Pina in 3D and The Kid with a Bike here, and another time I saw Bela Fleck play the banjo after a screening of Throw Down Your Heart.
