Easily the most underrated pizza place in Pittsburgh (and I've tried most of the famous ones). Quality wise better than Mineo's or Badamo (and I love them both), and far far ahead of Campiti's or that sorry excuse of a ripoff Beto's. Also vastly better than the chains, Pizza Hut, Domino's etc. I'd say DiCarlo's is about equiv to Fiori's if not slightly better and should be equally famous.
Yes, I made this account to spread the word about this place, it deserves more business. No, I don't work there haha
