Haven't been yet but will be in about 2 weeks. It sounds like really good food to me. I think it would be better to call it a Heroine's Breakfast than Princesses just because some girls can get too detailed about Pocahontas and Mulan not really being princesses, but that's a whole 'nother thing!
I hear that Jasmine, Belle and Aurora are regulars but that Esmerelda, Mulan, Pocahontas and Snow White also show up. Actually I think Snow White may be mroe of a regular.
You know your son better than most. I can tell you that I am taking my DS to Cindy's for his birthday breakfast and he's excited! We are also taking him to Princess Storybook. Of course, I'd be much happier and so would he if he could have Buzz Lightyear or another male hero, but we make do.
I am still hoping that DIsney desists with shoving Pooh and Friends down your throat and brings some other characters into meals that are appealing to boys, older children and even adults. But that's another thread topic too,
