I find deep dish pizza disturbing and this place takes it to an even more disturbing place, with filling and crust and cheese and crust piled over an inch high and a pie so big (and pie is the right word) that they give it its own stool at the table.
BUT the thin-crust pizza is astoundingly great, the sauce has fresh tomatoes and just a hint of heat, and the right amount of topping. I never, ever rave about pizza but I actually took my leftovers home and ate them for breakfast.
Also the service is unfailingly polite and attentive, almost unprecedented in a college down pizza joint.
So yeah, it's worth the wait even if you don't get the deep dish (and I wouldn't if I were you . . .)
