I have been to the F&W festival twice. Once with DD and DGDS (7+11) and once with just DH and me alone! You can guess which experience I liked best...

We attended the Epcot event several days of the trip. One day last year we attended a "Nosh Around the World" DIS meet event, sponsored by another DISer. What a grand time we had!
DH and I did the food plan and it worked out very well. On our Epcot days we only ate at the food booths....slowly walking around WS, sampling as we went. We used all of our snack credits for the booths. Since we did not dinner in a restaurant on our Epcot days that left us extra credits that we used at signature restaurants and we were even able to do HDDR at no cost!
We enjoyed almost all of the booths and thought the samplings were very tasty. I very much enjoyed the tea seminar that was given in the UK. We were each given several samples of tea to try with ideas on how to blend your own flavors. Mr. Twining himself (10th generation) was there from England and I had him sign one of the tea bags.

We attended the Samuel Adams beer seminar, but I don't like beer at all and D only likes specific brands, so well skip that next time.
There are several offerings for free tastings, seminars, etc. and you can check them out when you arrive at Epcot by just checking the schedule. Some of them fill very early in the day, (like the tea seminar) so be sure to check out what's available as soon as you arrive and get your name on the list if anything interests you.
They had lots of bottles of wine for sale, but thought the prices were a bit steep for wines I can buy elsewhere.
