I'm working in the Curtis Center this summer, and lunch has mostly been limited to sandwiches from Old Nelson's on 7th and Chestnut, or making the trek up to Capogiro when I can't go another day without it.
I'm looking for awesome, relatively cheap, and relatively quick lunch options. Reading Terminal is too far a walk for an everyday kind of thing, but I'm willing to trek a bit--say 15 minutes walk at the outside. Take-out is vastly better than sit-down.
Specifically, does anyone know of any particularly good carts in the area? Ethnic food is better than sausage carts or hot dogs, but if you know a fantastic one of the latter, I'd definitely be interested. I adore food carts, but I don't like to waste my time, money, and appetite on sub-par ones. Call me picky.
