UPN now has a license. I find the UPN pizza to be clearly different from the ones at Ops. The UPN center is wetter, the crust more chewy. For me, the Margherita suits the UPN style best. (My favorite pizza at Ops is the Pops.) I much preferred the dining room at the San Francisco UPN, which felt like you were in Italy, to the one on Orchard Street.
Agree that the Margarita suits the UPN pizza the best, although I also like the one with arugula all over it (totally diff kind of thing). I wish the UPN pizzas had a bit more variety to them- they all seem like almost margaritas to me.
I have no ability to suspend my disbelief while on Orchard Street to feel like I'm in Italy under any decor scheme, but maybe once they can bring me a bottle of red wine I'll be better able to imagine myself in Italy.
