Dedicated fryer .. was warned that it is next to the regular fryer so they did warn me about the slight risk of cross contamination but that they had never had any complaints from celiacs. I am celiac and took the risk and seemed to be fine from it. The burger was great too. I had tried to eat at this chain in Canada before and didn't have much luck but I was thoroughly impressed with the menu this location had. I would go back for sure!
