Biergarten is a buffet. No kids menu that I am aware of. I have not been there for a couple of years. The entertainment used to be a octoberfest type celebration. Men singing, I girl playing the bells, and a dance floor.
We really enjoyed Ohana. Everything was great there. Food and entertainment.
Cinderella's Gala Feast at the Grand Floridian was hilarious. The stepsisters were great.
