I'm pretty sure this is my favorite pizza in Pittsburgh. I'm so sick of pizza chains and pizza made on conveyer belts. Luckily, Fiori's still makes old school pizza that tastes great.
As others have said, the sauce is a little sweet. I personally think the sauce is what makes this pizza so good. The crust is thin and always baked to perfection and is never soggy.
On top of great pizza, Fiori's hoagies are some of the best around. My favorite is the Italian with banana peppers.
The only downside to Fiori's is the parking. It can be frustrating at busy times. Although parking can be tricky, don't let this stop you from eating an excellent pizza.
