I tried the gluten free pizza and it was very good. Z Pizza is my favorite GF pizza crust, but I think CPK's is even better than theirs.

Servers and chef knowledgable on gluten issue, however my options for dinner were limited to meat, fish and salad which is what I get at every other restaurant. I was hoping to try fried green tomatoes (which can be made with cornmeal), chicken wings or shrimp and grits but none were an option and no substitutions were available. I couldn't even have the mashed potatoes. Ended up having pesto mussels and a salad (boring). Chef left out the pesto on the mussels in case I had nut and dairy issues, which I don't and I covered with the server beforehand. Once they brought the pesto, it was better but not a great dining experience, especially for the price.
