The servers at Zinburger are very knowledgeable about celiac disease and eating gluten free. No menu but just ask about options. All burgers wrapped in lettuce and there is a dedicated fryer for fries. Delicious and great experience!
Edit 3/30/14 - expanded menu now with Udi's bun. No gf menu but every server has been knowledgeable. Mostly anything can be modified to be gf.
