We always go to La Côtelette and 95% of the time (or more) I've had zero issues, even though I'm one of the crazy sensitive celiacs who can't eat hardly anywhere. The fries are in their own fryer, though best to check in case they change their practices. Ask for "sans gluten" and if you're celiac and sensitive to cross contamination say it's an "allergie de contacte." Highly recommended!
