I have eaten at Pizzeria Uno's here in Chicago, it was pretty good but not any better than Lugiano's just down the street. And Lugiano's is cheaper. Also Lou Malnoti's (Schaumberg I think) is way better than Uno's IMHO.
Pizzeria Uno's also owns Dewey's Pizzeria, which is only a few blocks down from Uno's so I thought that was funny they didn't mention that. From what I understand they are the same pizzerias and the only reason they are in two locations a couple of blocks apart is because they needed more room and couldn't expand at the Uno location. I guess they felt a new name instead of "Uno's #2" was classier.
