When you arrive at the main Epcot gate, you walk past Spaceship Earth (for some folks, the big ball). There is a large fountain that is programmed to music. On one side of the fountain is Mouse Gears, a very large store. On the other side of the fountain (just past the Fountainview Restaurant), is Ice Station Cool. Looks kind of like an igloo from the outside.
What they have inside are Coke products, not Cokes. So there is no cola beverage that I can remember.
