Since your dining plan question has already been answered, I'll move on to the second part.
Kouzzina is pretty awesome for both breakfast and dinner. The breakfast definitely has some Mediterranean influence, but there's plenty to it that is more traditional, of that's what you'd like. They also serve a very good Bloody Mary. Dinner leans much more towards ethnic Greek, and it's delicious. They do a great job here all around. It can get quite noisy, though, so prepare yourself for that.
Rainforest Cafe is a place I'd only eat for breakfast (which you can only do at the Animal Kingdom location, by the way). They actually do a pretty excellent breakfast menu, and the restaurant seems significantly more laid back in the early hours. It makes the meal much more enjoyable than I imagine it would be any other time of the day, when it looks like a mob scene, and frankly, the lunch and dinner menus just do not appeal to us.
