I'll preface this by saying I lived in Chicago for a year and tried all of the deep dish establishments several times (Giordano's, Lou's, Gino's east, pizanos, pequods etc)
Maybe it's something in the water in the Midwest that can't be replicated here even though I'm in Arizona native, but the pizza is better in the Midwest I have to say.
However it's a solid pizza (the one that I ordered from Lou's in Phoenix) but I ordered a medium deep dish pizza and the cheese just clumped together and was pretty rubbery almost after it sat for 10 minutes. The crust is kind of bland especially if you compare it to Gino's East corn bread crust. Maybe I'll try the butter crust next time.
Overall decent but not necessarily crazy to go back and order again. Not thrilled with the cheese, pepperonis and mushrooms were good on the pizza.
