Pick your own pita fillings and flavorings (I go for the Greek). The soups are freshly made every day, and the shakes are close to the best I've had in Chicago. Good delivery service and, for the amount of food you get, the price is excellent, especially for college students. The amount of rice, however, is a bit excessive; I always have leftovers.
I don't like to eat on location, though, because it feels too much like a fast-food chain.
