Went to the Terroni patio yesterday for dinner at this location. I've been to all the locations and food at all three are at the same level, that level being very very delicious.
My go to dishes here are always the Funghi Assoluti which is a baked oyster mushroom served on arugula ... trust me, you must try this. The mushroom is covered with delicious bread crumbs and Parmesan and goes so well with the balsamic arugula. So so good. As a main, my favourite pasta here is the Tonnarelli alla Norcina (Italian black truffles, spicy sausage, pecorino and garlic ... ). Their pizzas are pretty good, my husband actually likes their pizza better than Libretto!
I've never had their meat main dishes, but I've heard from my friends who have that it's better to stick to their pastas and pizzas. Service here is great (our waitress was Maia and she was great!) and in the summer, their patio is the perfect place to have some wine and a delicious meal. All in all, a great meal every time, never a disappointment.
