The only gluten free thing on the menu is a side order that says "gluten free" with no description. When I asked the waitress, she didn't know what that meant either (not a good sign for those with gluten intolerance or worse). It turns out that they have gluten free bread that can be toasted on a part of the grill that has been cleaned for cross contamination. So, this is not really celiac friendly. I ordered the western sandwich with gf bread. It was not good.
They are very gluten aware. I'm not sure about safety for Celiacs but I did not have any reaction to eating there. I have a gluten allergy/sensitivity.
