I couldn't disagree more about the food. Mangino's has fabulous Italian food. In fact, we loved it so much, we ate there 3x during our 10 day trip. It was better and less expensive than the Disney Italian restaurants. Evergreen's is basic pub food. Decent sandwiches, appetizers, salads and pizza. No complaints. The onion rings are terrific. We didn't try the buffet. The breakfast gets good reviews, while dinner has been mixed. The quick service by the bus stop is pretty good, too. We enjoyed the breakfast sandwiches.
I was unimpressed w/ Evergreens, but Garden Gallery's breakfast buffet was pretty good. Also, depending on where your room is, it can be a pretty good hike to Evergreens! GG is right in the middle there- pretty convenient for breakfast.
