What a great find!
My wife and I were in Phoenix for the D-Backs/Pirates game and stopped in at ZPizza on W. Monroe (For other out of town people -- the entrance actually is NOT on W. Monroe -- it is on 1st (the East side of the block)).
We got the meat stromboli and it was really about as perfect as we could have wanted. The dough was fresh, light, soft, and delicious, as was everything inside.
We also sampled a few of the drinks on tap (self-serve taps were great -- ideal for being able to try several different brews, as they're billed by the ounce). I can't remember the names of the ones I tried, but they were dark and they were great. I'd take them over Guinness any day.
The next time we're back in Phoenix we're absolutely stopping again.
Open a ZPizza in Las Vegas! (Actually, it looks like ZPizza may have been here, but closed/left....so come back!)
