I waited 30 minutes for a 3-pita takeout order at RCK. There was no line when I got there, but I soon realized that everyone else in the place had already placed their orders and also were waiting an extremely long time for their food. Regardless, it wasn't *that* busy to justify such a long wait. I think part of the problem is the menu is too large for a takeout-type place (too many pitas with too many ingredients, lots of different side dishes) and there's clearly no system in place.
I don't care if this is the best pita sandwich in the world -- and it's far from it (the chicken is terribly dry; why do they not have a proper spit?) -- you should never have to wait 30 minutes for a falafel or chicken pita sandwich anywhere.
1-star for the wait, 3 stars for the food. Not worth it, at all.
