I don't know why they are listed. I called them to verify. To be clear, the gentleman told me that the falafel balls have no gluten or wheat flour in them, *but* they are fried in the same oil with the pita chips. If you worry about cross contamination, these aren't for you.
I still give them five stars because back in the day when I could eat gluten, they had far and away the best falafel around. Also, the gentleman who talked to me today apologized over and over, and he is now aware of the problem. They may make an effort to provide a dedicated frier.
