The Grand Floridian Cafe Heaping helpings of eggs, hashbrown sides the size of hubcaps, plentiful (and fresh) orange juice, and an idyllic setting all make for a great start to a great day. The tab, alas, can also be great. Expect to spend $12-15 or more pp.
Whispering Canyon at the Wilderness Lodge The wait staff's schtick can be a little irritating if you haven't had your first cup of coffee yet, but the food is REALLY good: steaming pans of eggs, sausage and bacon, served smack dab in the middle of yer table, plus a little table on the side with cereal and yogurt. I believe it's all you can eat. The energy here can be infectious, and get you rarin' to go for a day in the parks.
