Heya ADG! I'm in NYC so here are some tips:
For Sushi try walking along e.9th St, in the east village. It's a funky weird-angled street but it's just off 3rd Avenue and St. Mark's Place. There are about eight sushi places on there. The one I like has a downstairs and an upstairs and I can't remember the name. LOL Look up.
Hanging out anywhere along 14th St, from Avenue A east to 8th Ave. west down to Houston Street (again, anywhere between 8th Ave & Ave. A) and you can't go wrong. That big square of blocks encompasses both the east and west villages. Continue south of Houston (as you know, pronounced HOW-ston, not HEW-ston, unless you wanna get laughed at) and you go through SoHo (South of Houston), Chinatown, TriBeCa, etc.
Central Park, @72nd St. & Central Park West, is where you'll find all the John Lennon stuff, like the Dakota. Strawberry Fields is right inside the park entrance there. Museum of Natural History five blocks north, and the cool ass Hayden Planetarium, too.
I could go on and on, NYC is a wonderland of cool things to do and see. Have great fun dude!! Let me know when you're in town and let's meet for coffee.
