Hi Jaime,
Thanks so much for directing your question to the Moms Panel. I know how it it to deal with a picky eater; during our most recent trip to Walt Disney World, my 8 year old decided that he wanted to become very selective with his menu. Luckily, Walt Disney World restaurants do an amazing job at accommodating little ones which delicate palettes.
At
Coral Reef Restaurant in EPCOT. the kids meal menu consists of cheese pizza, grilled fish, grilled chicken breast, and meaty macaroni with carrots and celery sticks or soup of the day. French fries are available upon request. This menu is available for both lunch and dinner.
The Garden Grill, located at the top of the Land Pavilion in EPCOT, has a great kids menu as well. Their dinner menu consists of roasted turkey breast with whole wheat rice pilaf, steamed broccoli and sliced apples. They also offer oven-roasted chicken drumstick, baked macaroni & cheese, broccoli, and crispy sweet potato sticks.
I hope this helps you with your planning, Jaime. If you have any more questions, please feel free to as us at any time.
Have a fantastical Disney day!
