Shopping no, but you must, must, MUST go to Trattoria La Casalinga around the corner from Ugolini by Santo Spirito when you're there for lunch or dinner. It gets pretty crowded so lunch may be better, but regardless of the wait time it's worth it. Get the calf liver and some fresh veggies and thank me later. The most enjoyable place we went to this September. Down to earth, classic, soulful cooking. We loved it so much we went back two days later!
