I am not sure if any measures are taken to prevent cross-contamination. I do not have celiac disease, just an intolerance to gluten, so I do not need to worry about cross-contamination as much. To make my burger gluten free I always order it without a bun wrapped in lettuce.
I do know that they have an area on their website listing all their food items and what allergens (if any) are in them.
I order from this location weekly and the staff have always been great about customizing our burgers to keep me from getting “glutened”. They are one of the few places I can get “safe” fries. My usual order is a burger bowl with a ton of toppings and a small order of Cajun fries. They are my go-to in Westchester Commons for an allergy aware, quick dinner.
I eat here about once a month and feel fine afterwards. I always call them after placing my order to let them know I have an allergy and I’ve watched them change their gloves before preparing my food.
