My family and I went for breakfast a little over a month ago. Overall it was...eh. Pretty overpriced for one thing. The character experiance was good. However, I'm 14 and my sister is 16, so meeting the characters wasn't really at the top of our's and our parents "reasons for going list". Though we did enjoy watching the little kids.
Our server was excellent, very sweet and on top of things. My mom and my sister are both allergic to gluten, and the chef was very helpful and even made them special gluten free mickey waffles, which was excellant.
The rest of the food was not so great. The traditional mickey waffles were, as always, delicious, but everything else was...alright. (though some of it was flat out gross)
Overall, I can't say we'd really recommend it. In my opinion, Chrystal Palace is a much better character option. We've gone for both breakfast and dinner, and both times the characters, service and food were all outstanding.
