Excellent food! Everything we ordered exceed expectations. Soup was a stand out as was Ravoli della Nonna and the prosciutto pizza. Outdoor patio was fine on a chilly night thanks to heaters and beat the volume and chaos of the inside environment for this Middle Aged diner. Shout out to Justice for excellent service.

We got a really nice pizza that tasted very authentic and a Caesar salad with anchovies of course which was also very good. We sat in the window on these cute little backless stools which were surprisingly comfortable. Our waiter was friendly and talkative and made the experience even better. Try this place for yourselves.
