The Circlevision 360 movie in the Canada pavilion is worth the effort. I have always liked the Circlevision 360 movies, where the movie is played on movie screens all around the top of the theater, clear back to the old "America the Beautiful" movie at Disneyland. This one was every bit as good.
We had table service lunch at Coral Reef, in the "Living Seas" pavilion. One entire wall of the restaurant is a glassed-window view into the huge aquarium in "Living Seas". It was quite beautiful, although it was rather loud. The food was OK, but there are so many other good choices at Epcot that I wouldn't do it again.
I do want to offer one caution to people using forums as a resource. I had found a menu for Coral Reef that showed lobster tail and filet mignon. Since my daughter is nuts for lobster, we were looking forward to that. It turns out that, when they changed the pricing on the Disney dining plan a few months ago, they changed all of the menus. No more lobster, and the filet was replaced by a New York strip.
Epcot is really a bonanza for foodies. All of the international pavilions have at least one restaurant, and sometimes as many as three. For dinner, my kids went to the teriyaki place in the Japanese pavilion, and my wife and I got brats at the German pavilion. My kids, who do a lot of teriyaki meals, said it was one of the best they'd ever had. The brat was good as well, but I wish I could have been in the Biergarten...
