Oh man where do I begin?? Have you been to NYC before? There are the basic touristy spots that are kind of a must-have but my personal local favorites are http://xianfoods.com/
the greatest noodle shop I've ever been to. It's tiny and you'll probably have to stand outside to eat but oh my goodness its worth it. Right around the corner from there is NYC's longest operating bar http://www.mcsorleysnewyork.com/
You should check out some street fairs which always have interesting food and stuff to buy http://www.nycstreetfairs.com/sched.html
Time Out NY puts out this list for every season and it's full of great stuff and a lot of it is free like concerts, movies in the park, shakespeare in the park and really random but cool stuff http://www.timeout.com/newyork/things-t ... -city-2012
Let me think of more and I'll get back to you. This was just right off the top of my head.
