They no longer use a dedicated fryer. They are aware of gluten allergies and very proactive about making sure customers stay safe, but told me that although the fries are "supposed" to be gluten free, they share a fryer with wheat ingredients. Very frustrating, since I came here especially for fries. Otherwise, a good experience. I bring my own bun and have no issues with the burgers or shakes. Food is always top-notch!
