4.5/5.
If this place were *slightly* more affordable, I'd give it a perfect score. My friend and I shared the arancini, chicken liver mousse, rapini, and one of the soft cheeses. As my main I got the squid ink bigoli while she had the tagliatelle. We were impressed with all of the appetizers and side dishes, though if I had to quibble the the arancini could've used more salt. Highlight would have to be the chicken liver mousse (::Homer Simpson drool::) My pasta dish was excellent: the mussels and anchovies were fresh and tasty without being overpoweringly "fishy", and the breadcrumbs added a very enjoyable crunch. Preserved tomatoes lent just the right notes of sweetness. Also was a fan of the robust Bierno red of which I had two glasses.
All in all, this is definitely one of the most satisfying dining experiences that you can have in the city without burning a huge hole in your wallet. The servers are friendly and don't hesitate to answer any questions you may have about the menu. The ambiance of the restaurant is also warm and inviting without feeling too staid--probaly the perfect place to bring a date. That exposed brick!
