Note that you can always contact the head offices of any major fast food chain to determine which items on their menu are currently gluten free. Note that their menu's are always changing and as such, so can the gluten free status of any of their products. If you are currently dealing with gluten intolerance or celiac conditions, then don't be shy in asking restaurants about the presence of gluten in their foods. It is their duty to be polite and courteous in accommodating your request to the best of their ability.
On that note here is the response I received from Country Style's head office with regard to their menu
