If you're making the trip to Settignano, this is a great dining option (get off Bus 10 at the stop called Ponte a Mensola). The small, unassuming family-run trattoria is situated along a street and a tiny stream; if you sit outside (there are no views, alas), you might hear the trickle of the stream. The food is terrific, and though it is described as cucina casalinga (home cooking), only the portions are home-style. Service is prompt and courteous.
