Hello Amanda,
Welcome to the Disney Parks Moms Panel!
Hoop-Dee-Doo Musical Revue is so much fun; you're going to have a hand clappin', foot stompin', hootenanny of a good time! You'll get to dine on all-you-care-to-enjoy fried chicken, smoked BBQ ribs and many other yummy menu offerings all while being entertained by country western singers, dancers and comedians. Be prepared for corny jokes and lots of singing and dancing!
Hoop-Dee-Doo Musical Revue has a set menu and as a general rule, there are no substitutions. That said, you can always ask the Cast Member serving you to see if they can accommodate any special requests for your son. There are no guarantees, but Cast Members always try their best to meet the needs of Guests.
Another option that may work for your "picky Prince" would be
Mickey's Backyard BBQ. The BBQ offers all-you-care-to-enjoy country style food. Barbeque ribs, smoked chicken, hamburgers, hot dogs, corn on the cob, macaroni and cheese and much more. You'll have the chance to meet and get photos with Disney Characters, dance to live music from a country band, and watch some cowboy rope tricks!
Please stop back by if you have any additional vacation planning questions!
Happy Trails,
Susan
