Regina Margherita Pizzeria
Percussive. Don't fret. There is another pizzeria in Pittsburgh making absolutely authentic neapolitan pizza that is just as good as roberto's. It is called Il Pizzaiolo, and it is in Mt. Lebanon.
This is a full scale Italian restaraunt who's owner originally brought Roberto to the US to work for him. Roberto then decided to move on and open his own (very similar) restaraunt. I know that you will not be dissipointed in the pizza, even after growing to love Roberto's.
