Hi Tracy!
Thank you for visiting the Moms Panel!
Roaring Fork may possibly share the main kitchen at Disney's Wilderness Lodge with
Whispering Canyon Cafe, but most of the hot food is cooked to order in a smaller kitchen at Roaring Fork. Chicken nuggets and fries are currently on the menu at Roaring Fork, while Whispering Canyon Cafe has grilled chicken strips and french fries on the menu.
I know the cast members at both of these restaurants to be very helpful, and I would suggest you speak with your server at Whispering Canyon Cafe, explain your situation, and that your nephew will only eat items that are on the Roaring Fork menu. I think it is very likely they will try to accommodate your requirements.
I would recommend checking the menus on
www.allears.net - to ensure items are available at your chosen restaurants.
If you have any other questions, please come back and ask me - I would be happy to help you plan your magical vacation!
