Excellent option for gluten free. When traveling, I try to live by the mantra, "Don't eat in super-touristy areas." Well, you can't get much more touristy in Siena that on Il Campo, but this place is the exception to my rule. Great location, great view from the outdoor seating, and excellent food, including GF pasta. Also, ask to see the wine cellar. It's worth the walk inside. Note: they do not offer GF pizza. They are under new ownership (we were told). Maybe they did in the past?
