This is one of the best summer pLaces in Pittsburgh!
The pros: The food on the first floor is simply delicious, it's much much more than a "meatball place" (but oh, those meatballs!). Drinks are good too, nothing special, but definitely standard. The rooftop deck is fantastic (but don't expect to get a seat Thursday through Saturday).
The cons: the food upstairs isn't quite as great as the downstairs and you can't get the meatballs (sigh). The drinks are craft, but I'm a sweet drink person and there isn't much for me.
I recommend: eat downstairs (get the broccoli, the pesto sauce and the mashed potatoes), then spend the rest of your night on the third floor.
