I had the good fortune of visiting Italy this August. We spent time in Florence and in a country farmhouse near Mensano (party of the Belmond Castello di Casole). On this trip, I developed a better appreciation of the local Chianti wine.
If you want the serious nitty gritty on where to dine in Florence, I know a guy. However, this list consists of a mixture of guide recommendations, my own research and best of all, happy accidents (the best part of travelling). I heartily recommend any of the places listed below.
