Sorry, if you want to dine there you will have to have a ticket to the park. You may want to try one of the fine dining establishments in the resorts.
In the Epcot resorts there are Palio's, The Flying Fish, The Yachtsman Steakhouse and Shula's.
Over near the MK, you will find Narcoosee's, Citricos, California Grill, 'Ohana, Kona Cafe, and Artist's Point.
At the Animal Kingdom Lodge you may choose from Jiko and Boma.
Bon Apetit!
