I had breakfast there on the 8th Jan.
Arrived around 9:10am for my 10:10 ADR and just watched the crowds - they never really let up. Quite amazing how many people breakfast late in the day - did expect after 10am to be quieter but no - still piling in after 11am.
Got my pager and was paged around the time of my ADR.
The waitress was very helpful and constantly refilled the orange juice and made sure I was fine.
Food was warm but newer food was put out and I tried everything first time around. Usual pancakes, scrambled eggs, fruit, bacon, home fries, Mickey Waffles etc and it cost $24.99 + tax + tip.
Quite noisy what with tables full of kids (95% Spanish speaking) but still got photos with the characters.
Found the place to be a bit open for my liking. You're easily overlooked by everyone inside and outside, and with the open wall for the monorail, there are loads of sparrows flying about, on the floor, tables etc.
Did 1900 Park Fare the following day and a lot better. Looked posher although wasn't keen on people with electronic pads standing around looking like security guards. Food was much the same although toast, bagels, strawberry soup and an omelette station were there. Better atmosphere overall and cheaper at $20.99 + tax + tip. Service was better at Chef Mickey's to be honest.
Characters did take longer to come around though.
To be honest, if it's just meeting Mickey etc you want, probably best to go to Epcot and meet them all there for free. At least you don't get half of Brazil or Mexico in the background of all your photos!
