Badia a Coltibuono?
I totally disagree. The location is lovely, the drive from Greve is pleasant and the food is very good. Plus, the menu offers a number of options that are strikingly different from the usual trattoria fare in Chianti, especially in the fall when the harvest has come in. The estate bottled wine, particularly the RS Riserva, is excellent.
I say go and have a great and memorable lunch.
