I was in Pittsburgh for work and my coworker chose this place out of the blue. We were not disappointed!
The food was nothing short of amazing and the service was incredible.
We had the gnocchi and the bolognese as well as the veal and mozzarella stuffed meatballs. Dammit! So incredible!
So if you're downtown and you want excellent Italian, Sienna On the Square is the right place. A full meal with drinks for 2 people was less than $100 before tip.
