Hi Zane!
I understand picky eaters as I am one of the pickiest eaters I have ever met! I have also been known to order off of the kids menu at restaurants around Walt Disney World and even on Disney Cruise Line! I assure you that at all of the character dining restaurants, there is always something on the adult menu I like.
Most character dining restaurants are buffet or all-you-care-to-eat style, which is nice since you can pick and choose what you want to eat. Restaurants like Chef Mickey's in the Contemporary Resort have a special kids section that features pizza, Mickey mac n cheese, chicken tenders and fries. Chef Mickey's is my favorite for character dining. You're also pretty safe at any breakfast as well. The standard eggs, pancakes, waffles, pastries and fruit can be found anywhere. I recommend Crystal Palace in the Magic Kingdom or Tusker House in the Animal Kingdom for breakfast. This isn't a character meal, but I highly recommend 'Ohana in the Polynesian Resort for dinner. It is (oh my goodness) so delicious and is my #1 favorite restaurant at Walt Disney World.
There are tons of options for you to pick from. Take a look at all of the
character dining restaurants available. Do make your reservations as soon as you can because these restaurants book up fast!
Have a magical day!
