Go to a Rangers ice hockey game at madison sq. garden. Go sit down by the ice before the game starts!
Check out greenwich village, its full of cool little restaurants like The Ear.
Visit the brooklyn brewery (tho ive heard rumours its moved...) if not then at least drink a lot of their beer and / or visit one of the Heartland Brewery bars (empire state building / union sq for example).
Go to a flea market (like Hells Kitchen or the indoor one in Chelsea), its full of weird stuff and weird people.
Take the ferry to staten island (and come straight back!) its not worth going to Liberty Island unless you can go in the statue (not sure if theyve reopened it yet).
Go to the DailySHow and Colbert report websites and try to get into the audience! its free but you have to take what you can and hope for the best. I went to both shows (Thanks to TaBanger!) and it was great.
and lastly try and meet up with Jason Roth. That guy is a legend.
okay thats all i can think of now. that last one is optional btw
