Banzo knows their beans.
I've been searching for great falafel ever since Caspian Cafe shuttered years ago and I've found it!
I've had their food delivered to work and my apartment a bunch of times and I finally made it to the cart(check out their fbook or twitter accounts for specials and location). The line and wait for food can be long, but please, I BEG you, to stick it out. I've had a chance to explore most of their menu and it's all wonderful.
The food is so reasonably priced, especially give the portion size. You can have a pita sandwich with your choice of filling that comes in a well-designed to go box, or upgrade to a hummus plate (some of the best in town), or a platter. Nothing will set you back more than $10.
I saw that they're going to be open for late night food soon and I can't wait!
