I was worried about the Biergarten for my DD8 and DS3, but they loved it!! They had to go dance on the dance floor and they really liked the food. The beef roulades were a big hit with both kids, as well as the apple strudel and vanilla pudding. They also liked the tomato salad and the cucumber salad, and of course the spatzels and the potato dumplings. DH thought the pork roast was one of the best he's ever had.
Another one to consider would be the Garden Grill at the Land Pavilion. It's a character meal with Mickey, Pluto, Chip, and Dale. It's also served family style, so you can stay at the table. The menu is a salad, platter of turkey, beef, and fish with mashed potatoes, rice, some veggies, and an apple-berry cobbler for dessert. The kids get chicken drumsticks, mac-n-cheese, sweet potato fries, and Mickey mousse for dessert. It's Dinner only.
We did both on our trip 3 weeks ago and had a great time at both meals!!
