I gotta go along with isppilot on this one, you'd be cutting it way to close trying to make it downtown and back (it take 45 minutes to cook a deep dish). Better choice to go to one of the places, Gino's, or my favorite Giordano's in Rosemont- maybe 15 minutes by UBER.

And isppilot, I will admit I do enjoy a thin crust now and then, although it takes some getting use to, eating pizza with my hands. *laughing*
