A list of fresh fruit locations I've found throughout Walt Disney World's four parks:
Magic Kingdom:
Starbucks on Main Street, USA - for more on Starbucks at Disney, head here
Aloha Isle in Adventureland - pineapple spears
Chesire Cafe in Fantasyland
Prince Eric's Village Market in New Fantasyland - this is basically the Magic Kingdom Mecca of healthy food finds
Gaston's Tavern in Fantasyland - fruit cup
Auntie Gravity's Galactic Goodies in Tomorrowland
Tomorrowland Terrace - side dish of apple slices
Liberty Square Market in Libery Square - just as good as Prince Eric's Village Market in terms of healthy food finds
Epcot:
Fountain View (aka Starbucks)
The Land cart
Kringla Bakeri Og Kafe, Norway pavilion - fruit cup
Yorkshire County Fish Shop, UK Pavilion
Electric Umbrella, Future World - fruit cup
Sunshine Seasons inside The Land
various nameless(?) stands throughout the park
Hollywood Studios - please note that there are MANY changes coming to this park over the next few years what with the addition of Star Wars and Toy Story lands, so this list may be updated more frequently than others as new things pop up around the parks:
Anaheim Produce, across from the Beauty and the Beast show theater
Starring Rolls Cafe, Sunset Blvd. area
The Trolley Car Cafe (aka Starbucks)
various nameless(?) stands throughout the park - most of the ice cream stands and popcorn stands carry bananas, oranges, or apples. One of note is located near Jedi Training Academy and Star Tours and another as you’re approaching the area where Star Wars Launch Bay, Voyage of the Little Mermaid, and Disney Jr. are.
Animal Kingdom:
Harambe Fruit Market
Creature Comforts (aka Starbucks)
Kusafiri Coffee Shop & Bakery
