Anyone been to Epcot’s Food and Wine Festival?

I am considering going to Epcot’s Food and Wine Fest. However, I am trying to figure out how much it will cost and if it’s worth it. The description on their website is very vague as to what you pay for and how much. I know the general admission but then do you pay each time you taste at a new location. If yes, is it reasonable or is it like purchase an entire meal/drink at each place?
