Jindy, the F&W is simply nirvana. That's it. Nirvana (not the band either).
For 6 weeks from the start of October to mid November (use to just be October), Epcot holds the F&W. Many different things go on, but the jist is, there are approximatly 30-40 booths set up around the World Showcase lagoon featuring different countries/ areas of the world (i.e. Spain will have it's own booth, but Norway and such will fall under the Scandanavia booth). Each booth has sample size offerings of food from that area as well as beverages, usually alcoholic in nature, but not always (Mexico has it's watermelon juice and Florida will have frozen grapefruit juice). The cost for each sample of food is anywhere between $1 to $4. A 1oz sample of wine will be about $2-$4 about the same for beer. There will also be free classes and demonstrations throuhgout. There are special dinner parties and events throughout WDW at various resteraunts. Last year they had a wine walk-about featuring various wines from Australia. The year before that was a special exhibit about Andalucia Spain, before that was South Africa.
You can also get the recipes for almost everything you try. They will also sell the bottles of wine that you sample, which is pretty significant, since some of them are bottles you can't find in the states without selling your first born.
There is also a champagne booth, use to have chocolate with it, but last year the cognac booth had the chocolate. There's usually a California booth where I snag some awesome polenta. The Polish booth is quite popular, you can get eh pirogis there, but for Florida they're great. The Irish booth has this wiskey flan that is down right wrong when you have it with O'Mearas Irish Creme (IMHO it's better than Bailey's). What else?
They'll also have a beers from around the world as well as around the US. Since Budwieser stopped hosting the beer thing, there has been a push for microbrews which is good.
There are special shows throughout, you can get priorty seating with the dinner packages.
It's just amazing. It really is the best thing Disney does for it's adult fans at WDW. The Flower and Garden show is nice, Christmas is beautiful, NYE is fun, the F&W festival is all of the above.
Did I explain it enough?
