I'm dying for Falafel. I'm stuck within a +/- 5 block radius of 56th Street. I'm totally up for going to a cart, but I was hoping some Chowhounders might have some suggestions. I've been to Pita Grill (Good carrot tahini, bad Falafel and worse prices) and in a moment of desperation I even gave the Pick-a-Bagel stuff a try. I need a reputable fix in the area.
