Cape May Cafe at Beach Club has a wonderful character breakfast. The food has a good variety, is tasty, and replenished often. (I hate overheated buffet food.) The characters are great too. It is a great experience overall.
Kona Cafe is a kind of normal sit down restaurant that you would find in an upscale hotel, but the Tonga Toast. WOW! Its a nice environment, and ideal if you are going to MK. I think the real treat though is the Tonga Toast. Did I say WOW! I'm not a coffee drinker, but I think Kona is one of the few places will real coffee and not Nescafe.
Whispering Canyon Cafe has a good country skillet breakfast too.
