Some people aren't. I wasn't sure what you are into. The age limit is 21 and most of the good clubs are 21 and up. Fake IDs work in nyc make sure you get a good one though its worth the extra money. If you know people in NYC, you can get into private parties and whatnot. Those are usually the most fun. You just gotta know the right people.
The place I always go to eat for falafel and I think they have shawerma if I'm not mistaken since I don't really eat it that often is Mamouns. It's amazing since it stays open until 5 am and after a long night of partying, it tastes amazing. I never have ate there sober/in the daytime. If you are looking for a place, I'm sure you friend knows it. It's on Macdougal St near Minetta Ln.
