travelbug24,
If your traveling with kids, I'd definately do Goofy's Kithchen. It's actually a brunch with breakfast & lunch items. This meal has the most characters and is fun & loud. (Characters: Always Goofy. We also had Jasmine, Baloo, Turk, Mad Hatter and Chip & Dale in the front).
If it's for 2 adults, I'd definately go to Storytellers Cafe. The food selection is the best breakfast buffet I've tasted. They had made to order omeletes, Lox & bagels, eggs benedict, asparagus, chicken sausage, all the regular breakfast fare and much more. The characters stay at the front to greet guest and every 1/2 or so they have a parade through the restuarant with the kids. It's alot quieter than goofy's kitchen, but my kids really enjoyed the food. (Characters: Always Chip & Dale plus a few others we also had Pluto & Donald).
I've never eaten at PCH Grill, but I heard it's a regular breakfast but they include some traditional asian fare.
