Ditto on Blue Bayou!
I was in DL for 4 days in October 2001, and boy did we eat!!! There are so many wonderful choices. Some of my favorites:
Storyteller's Cafe in the Grand Californian -- we ate the breakfast buffet and dinner off the menu. They also have a dinner buffet which looked wonderful, but we weren't hungry enough. EVERYTHING was great. The quality of the food was very good, and the atmosphere nice, but casual enough to wear jeans or whatever you wore to the park.
Naples in Downtown Disney -- we ate lunch here. Again, the food was terrific. This is an Italian place, and the food was just plain yummy. The portions were quite large too. BF and I shared a salad, he had a pizza and I had lasagna. BF only ate half his pizza and he was full. I ate most of my lasagna, but only because it was so good! I think if we each had a full salad and shared an entree it would've been perfect.
La Brea Bakery in DD -- we ate a quick breakfast here, but it was memorable. You order at the counter and take your food outside. BF ordered a couple of pastries, and I had the lox and bagels which were awesome! Again, we probably could've just bought an extra bagel and shared, the salmon portion was huge.
If you're looking for more of a fine-dining experience, Napa Rose at GC looked great. We didn't get a chance to go there, but the menu looked wonderful, and we took a tour of GC which included Napa Rose, and it was beautiful.
Hook's Pointe in
Disneyland Hotel -- Another great dinner, and a little more on the fine-dining end.
