My husband is the Celiac of the family & is always scared to eat at a new place. He doesn't like explaining why he can't have this or that & asking questions but he did at City Diner & both times we are there both waitresses knew what gluten was & were able to answer questions honestly & even had the cook come out & read an ingredient list!! First time he's been able to order something fried & it be totally GF!! Even the oysters were cooked in Zatarains fish fry. We were told they even have a seperate fryer for French fries. The food is so delicious & fresh! Staff was amazing!!!!
