Its weird that those were your choices because my family seems to go to all of those places everytime, all personal favs of ours.
LIke it was mentioned, the Garden Grille was great for home cooking, and had great theming. The place rotates and you can overlook Living with the Land. Its calm, and relaxing, and great for kids. Again, if they changed the menu I can't speak for it, but it used to be great.
Teppanyaki is like your standard Bennihana's type place, but with Disney class of course. Great food, great dinner show, and a great view of the World Showcase. I've gone once everytime for all 8 of my trips there.
Liberty Tree is similar to the GG in menu and character dinning. Its family style, and very good. Again, great for kids.
We went to Breakfastosaurus for the first time last trip and it was fun. Very large and diverse breakfast menu, and really fun theming inside ( i'm a designer, so i like interesting interiors to places). Also, I belive if you make the ps early enough, you get early entranbce to the park, and a jump start on hitting any ride you want.
Hope that helped.
