528 5th Avenue, San Diego, CA 92101
This is possibly the best gluten free hamburger I've ever had. They have gluten free buns and a separate gluten free menu. The service is great, the atmosphere is laid back and the waitstaff are knowledgeable and friendly. They will specify to the cook staff if you have an allergy.

This restaurant has helpful and fairly knowledgeable waitstaff but they do not have official training on celiac or gluten intolerances.
