According to Wikipedia, yeah... UNO's invented chicago style pizza. but honestly, i don't care who came first. I do know that every UNO's I have eaten at pales in comparison to the smaller chicago style pizza chains and local restaurants in the city. Maybe UNO's was great too at one time, but I'm sure (like most other chains) that when it became corporate or a chain or whatever, that it lost a lot of quality. I mean, people outside of the midwest probably wouldn't know what good chicago pizza is or isn't anyway. if UNOs shows up in a town where there was nothing like that before, I'm sure people would love it. There are a TON of Chicagoans in the area though... besides the fact that a lot of Grand Rapidians go there pretty often. If they opened a Giordanos (it does actually have some restaurants outside of IL), I can pretty much guarantee it'd get more business than UNO's.
