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