They have a dedicated GF fryer, but did there was still a risk of cross-contamination. When I called in my order the girl on the phone checked with someone else to make sure she was flagging it correctly, and the items I asked for GF came out marked with purple stickers.
Got traditional wings with Garlic Parmesan sauce (most of the sauce are gluten free) and fries, and didn't have any major reactions afterward.
