Hi Jaynee!
Welcome back to the Disney Parks Moms Panel! I am thrilled you have visited us again and that I now have the opportunity to answer a planning question for you.
On my last trip "home" my step-dad joined us and it was great to watch the Disney chefs accommodate his gluten allergy seamlessly at
every restaurant we visited. It didn't matter if it was quick-service or table-service, they jumped into action and quickly made sure he wouldn't feel left out. In fact, one of the chefs told us they enjoyed preparing for allergies as it was a chance to show off their culinary expertise in making something customized and delicious and it lets them step out of the kitchen and interact with the Guests. Back to your answer, yes,
Casey's Corner will happily accommodate your gluten-free diet.
I hope this helps in planning your Disney dining, but if there is anything else I may assist you with, don't hesitate to ask. Have a wonderful trip, Jaynee!
Magical Wishes,
Lauren
