Although I haven't been to Ice Station Cool yet, from what I've read so far, it sounds like a replica of the top floor fountain area at World of Coke in Atlanta--a.k.a. the Coca Cola Museum.
I've been to World of Coke twice and, if this is the same set-up, what you're getting at Ice Station Cool are Coca Cola Corporation products that are sold all over the world.
For the U.S. drinks, you can get Tab, Fresca, Mr. Pibb, and Mellow Yellow--stuff that we are hard-pressed to find in California.
But the international flavors are interesting. I like the Fanta products, mostly citrus flavors like Orange and Tangerine, particularly from Germany. Do they have those at Epcot?
And Beverly (the Italian apertif) is truly nasty stuff. We have photos and videos of several individual's first reactions to a sip--not surprisingly all grossed-out faces. I think this stuff is used for an Italian version of "Candid Camera."
My kids love World of Coke. We have family in Atlanta who are ironically joining us for our upcoming WDW trip and we're all looking forward to getting free Coke products at Epcot. Hey, it beats paying $3.50 for a half litre bottle, doesn't it?
