You should get in charge with Brenda Bennett, or someone at food services. Each CS restaurant will give you the ingredients in the food. However, someone at food services can get you the list of which CS restaurants carry GF mac and cheese, GF pizza, GF hot dog buns and rolls, GF cookies and brownies and treats. There is atleast one CS in each park that will have these things on hand all of the time. Good luck...you should have no problems, especially if you are prepared!
