I think it really depends who is working that day. I called ahead and was told no GF menu but the wait staff can recommend GF options. My waitress didn't know what gluten free was but did go to the kitchen, where they said they didn't know either. They have a very large menu and are very willing to hold anything you don't want. I ordered my go-to for Mexican and didn't have any reaction.
— Not very
— No gluten-free information on the menu
— Not Much
— Excellent
