DH and I went a few years ago. I really liked it....he thought it was okay. The flowers, fountains and music were a lovely setting for a myriad of scrumptious buffets. They had a little of everything...seafood, breakfast foods, middle-eastern.....I don't remember the specifics but I do remember filling my plate...again...and again...and again.
The chefs were there to discuss recipes, cooking, etc. It was held in the odyssey pavillion in Epcot near the mexico entrance to world showcase. Not sure if they still have it there.
The flowers were amazing. Understand, though, that I worked for a floral company for 18 years and have been exposed to this type of over kill before at floral shows and conventions. There are arrangements, vignettes, ice sculptures and fountains at every turn.
While I thought it was worth the money...it's not something I would do every year. Been there...done that! I don't recall how often it was held or how much it was....sorry!
