The Kitchen has a good breakfast buffet with made or order omelettes, fruit, pancakes, bagels, etc, etc. It included juice and coffee. It's not cheap, but I thought it was worth it for a good breakfast.
We just got home yesterday, and found that what was quickest for us was just getting our breakfast at Emack & Bolio's in the lobby. There is Starbucks coffee in there, and you can buy chocolate milk, juice, etc. for the kids. They have fruit, donuts, bagel's (there is a toaster there too if you like to toast your bagel), cereal, etc.... Usually I was the first one done, so I'd just go down and get what everyone wanted and brought it up to the room. It worked out very well for us...... Have a great time!
