Where to find great pizza?

[marypaintscars]

My parents are coming up from AL this coming weekend, and have requested that we go out Saturday night for some really good pizza.  So, where do you suggest we go?  I live in Butler County, but don't mind driving wherever.  Problem:  they're old, and complain about stupid things, so preferably somewhere fairly clean, with no smoking, and no loud live band.  Seriously.  I don't want to hear the complaining...

Thanks for any and all suggestions!

Edit:  My search has found that Mineo's claims to be the best in Pittsburgh.  What are they like?
