I have the receipt right in front of me -- we ate there on Saturday. It was $16.99 for adults and $8.99 for kids. My 15 month old was not charged (though it was noted on the receipt as Infant Breakfast) The total for two adults and a 4-year old came to $52.55 including 2.58 tax and $7.00 tip.
It was an expensive breakfast considering my son only ate a waffle, a few pieces of bacon and some watermelon. He didn't drink his juice. My husband enjoyed French toast, sausages, eggs, coffee and took an apple for the road. I had a Mickey waffle, some scrambled eggs, a few pieces of bacon and some fruit. (The baby took a few bites of a waffle.)
We arrived at 8, for an 8:10 PS, and the food was pretty good -- warm and freshly made. I've read mixed reviews but it wasn't as bad as some people have said. We thought it was well done -- we just weren't very hungry. For what we paid, I wish we had eaten more, but, perhaps it's better that we didn't... fewer vacation-pounds to lose.
Of course the same breakfast at home would have cost around $15 at our local breakfast place, but we
were at Disney, had fun, and the character interaction was
great. I'm glad we did a character breakfast despite the expense.
(I heard from another guest staying at our resort that the Prncess Breakfast was better -- but I have boys, and they're decidely NOT into princesses.
