I'm all about some yummy TS dining when I'm in the World, but I have to say I've enjoyed some tasty CS meals at AK. Tusker House has a chicken salad that is ginormous - seriously. Could not finish it.
Rainforest Cafe is fun, but I think the animal noises, etc are a little much, sometimes. And the prices are a bit over the top for what you get. I think breakfast is by far their best meal - yummy and less expensive than other meals there. Try the last breakfast seating after morning EMH at AK and you'll be all set until dinner.
