There is a separate gluten free menu. I was surprised at how much was on there, as a lot of sauces/spices are usually a no-go for me.
My server wasn’t super knowledgeable and ended up serving me a side of gravy that did contain gluten. I would recommend holding on to the GF menu throughout the entire night if you’re eating here to reference throughout the night. Most of their main courses are not celiac safe (there is a shared grill top), but their bbq is allegedly safe from cross contamination. I had their side of mashed potatoes (with NO gravy) and had no reaction. Their bbq sauces are all GF.
