They have a printed list at the front containing items that contain gluten. I ordered the Salmon salad, and the server had them grill it in a separate pan, not on the main grill.
I told our waiter that I had celiacs and he and the chef were very accommodating! They even baked me my own corn tortilla chips so I didn't have to worry about cross contamination from the fryer. They also made my favorite (steak quesadillas) gluten free. While I am hesitant to eat anywhere but Ruggles since I found out I had celiacs, Cyclone's definitely went above and beyond to make sure I felt at ease dining with them!
