Serious about the 40/40? Why not somewhere that doesn't have insane prices? The last time I did a Clutchfans NYC meetup it was 2007 for a playoffs games against the Jazz. It was a good time. I would try to meet up somewhere but 40/40 hell to the no!
Blondie's was a great time. Actually just did that before with some other CF's: http://bbs.clutchfans.net/showthread.php?t=253160 Had sound, the game was on a large-screen. Good place. I would recommend that place.
