If you are looking for a seafood restaurant around Florence, Trattoria Del Pesce in Bargino, just a couple minutes off the FI-SI, is an excellent choice. We had a birthday dinner there the other night, and most everything was excellent and fresh. The wine prices are barely marked above retail. The quantities were actually too much - we never would have ordered seconds if we knew. Dinner for 4, with a bottle of white, 3 bottles of water, many plates, and a few desserts was just over $200 U.S. Highly recommended.
