We love Goofy's Kitchen for breakfast. It has a large variety of good foods. Pleanty of breakfast items to choose from and there are other non breakfast items as well. There are almost always green salads and dressings which makes me happy. We have yet to try Goofy's for lunch or dinner.
The Blue Bayou has an awesome atmosphere but the food for lunch and dinner is just okay. At lunch you can get the Monte Christo Sandwich which is real good. It is not served at Dinner. Salads are good here.
I have not tried the Plaza breakfast (we are always over at Goofy's Kitchen) but lunch and dinner (which are the same menu) are good and the setting is pretty.
Another good place to eat is the Storyteller Cafe at the Grand Californian Hotel. If you are at DCA it is an easy 2-3 minute walk from the side entrance of the park. Has a nice variety of food and a nice setting.
At DCA there is a character lunch and dinner at Ariel's grotto. I really like the food here and the interior is nice. Or you can choose to sit out on the dock. There is a limited menu but everything I have had was good....except I can't handle eating the cotton candy at the end of the meal!
You can get good salads and soup in a bread bowl at the Pacific Warf Cafe at DCA.
Back at
Disneyland for counter service places, Red Rockets Pizza Port has bland, expensive pizza but decent pasta. The French Market in New Orleans Square has some good food and I like their pasta as well. In Adventureland there is a little place to get skewers / kabobs that are really good. It is called the Bengal BBQ. In Frontierland is Rancho Del Zacolo which I wish was better. It is Mexican food but somehow just missed the mark for me. They also have BBQ which we have not tried. The setting is nice though.
