My fiance is from Joliet, IL and swears that Chicago pizza, in addition to being deep dish, also puts the sauce on TOP of the cheese. Born and bred a New Yorker, I find that concept totally alien. Is this true? Does Uno's serve it that way? (Never been.)
Could he be referring to the double-crust variation (not what Uno serves)? This has a crust on the bottom, then the cheese and other toppings/fillings, then a second crust layer with the sauce on top of that.
