This is the only place in New York that I know of where you can cheaply play some air hockey. Does that warrant a post? Umm... derr?

Yes, it's tiny as hell but it's open 365 days a year (which I consider notable in this city). It's pretty much a basic arcade where the games are relatively cheap and the prizes you can get with tickets are basically trash (but I'll assume you're not going to an arcade for prizes). The place is filled with mostly kids and teenagers (not the obnoxious type of teens - but the nice ones who take each other on cute dates and laugh loud), so it's a pretty fun place to go with someone for a game if you're in the area.
