Before you eat or place an order know that the waitress can bring you a binder that has every item that they serve and the possible allergens associated with that food. From there, you should be able to figure out if there is something that you can eat or not. It's quite extensive.
I ordered the breaded catfish. Although it was fried and soy I think it was gluten-free.
There are several gluten-free options although I'm not sure of the safety in the back kitchen. The catfish was very good!
— Gluten-free items are marked on the main menu
