I love pizza..in the 10 years I have been Gluten Free it has never been easier than it is now to find good GF pizza at restaurants and pizza places – so venture out. In the SF Bay area Extreme Pizza, and Willow Street Pizza are two favorites. Just remember it is thin crust most of the time and if you want extra toppings ASK, many places will add a little ground meat or chopped ham if you like..They often err on the side of less because it is not always easy to get assurance that the toppings are GF.
I use the www.triumphdining.com to find Restaurants and I rely on Yelp and other reviews to help me out.
