Hi Lisa!
Epcot Theme Park covers over 300 acres and is divided into 2 parts: Future World and World Showcase. Your admission to Epcot covers the entire Park.
Future World is home to a lot of exciting attractions like Soarin', Test Track, Spaceship Earth, The Seas with Nemo and Friends and much more.
World Showcase has 11 different countries and is bursting with culture and wonderful restaurants.
If you wish to eat in any of the restaurants inside Epcot, you will need to use a Park ticket to gain admission.
