This is going to sound funny, but we have always had good food and great service at the Denny's across the street. We often end up there at the end of the night for ice cream, rather than waiting in line in Disney. The prices are a bit higher on some things, but still a good value. We have also had good meals at IHOP. I would skip Millies and Mom's!
We prefer the Rainforest Cafe in South Coast Plaza. We ate at the one in Downtown Disney in March and the service was horrible (as was the manager we were told to complain to). My husband doesn't want to set foot in another one ever again!
We never miss a meal at Knott's Berry Farm. Either the chicken dinner, or Sunday buffet, though the buffet wasn't as good as usual this trip.
We tried Marie Callender's on Euclid and was pleased. We were there for the lunch rush, and had good service and good food.
Oh! Try the hotel restaurants as well. Goofy's Kitchen was wonderful. Alot better than I remembered. I would recommend it for brunch.
