A couple of tips when it comes to Epcot..there really isn't much food that is bad in Epcot its all fantastic..if you want A LOT of food and a fun time eat in Germany...the pizza at Via Napoli is absolute FANTASTIC..and they are pretty big pies and delicious. The food in Mexico is good, but its standard fare when it comes to Mexican food. The hibachi in Japan is good...but my main suggestion eat the Pizza in Via Napoli...enjoy your dessert in the bakery in France....get your beers in Germany and the Rose and Crown Pub in England...and if you have space and time for a Grand Marnier Slush in France too.. go for it
Also make sure you go to Club Cool, its a soda sampling station in Epcot, and make sure EVERYONE in your group tries Beverly except for you and laugh at their reaction.
