There are a number of special eventswine tastings, chef's demonstrations, etc.that are held in Epcot, as well as special food and drink booths set up around World Showcase. Most of the booths have samples of the cuisine and wines (or beers) from the countries they represent. The countries are not limited to those that have a standing presence in World Showcase either. I can't recall all that we saw two weeks ago, but in addition to the WS countries there were booths for Australia, Southeast Asia, India, Ireland and others.
We were there on a warm Saturday night, so lines at most booths were VERY long (some looked like they could take 30 minutes or more to get through). Also, prices are appropriately Epcotish ($7+ wines, etc.). We had our two kids (DD10 and DS7) with us, so long lines weren't on our agenda and we didn't get the full impact of the festival. There were many, many people who obviously were getting more than their fair share of the benefit (from the wine part, at least), however.
