My wife and I searched "best gf pizza" in San Diego and this was what we landed on.
The gluten free crust here is homemade and a small pizza can feed 2 people (maybe add an appetizer if you're starving). Great thin crust - I don't eat GF but my wife has to (Celiac), and I even ate the edges of the crust! I rarely do that with GF Pizza.
One suggestion - order with extra cheese. They use a high-quality cheese but we would have liked more on it than it comes with standard.
Also, the restaurant is in a very fun location. If you haven't been to North Park, check it out!
