I haven’t done the dinner there, but the food at Park Faire is decent, not great. Just “faire”. LOL
However, you are right, the characters are the best there. They have hands down the best Mad Hatter at Disney. He is the one in my avatar with my daughter. We still laugh our tails off just thinking about that guy. I don’t think he is there for dinner, but great nonetheless.
What specific character are you looking to see?
