Does anyone have knowledge of what these schools offer in this regard?
All the cafeteria style places at USC have some GF options. Then of course there are the items that are GF at the individual places like chick-fil-a and Panera, etc. There is a dietician you can contact to talk about options. USC requires a foodplan as a freshman, but it doesnt have to be the “all meals” option. Many dorms are suite style that would give you access to preparing your own food if that’s your comfort level.
