I second that! It's the only restaurant we did both trips. The salads and cold veggies are great, the cucumber salad is to die for. It is a great place for picky eaters, the snitzel is a nice breaded chicken, and the rotisserie chicken is good too, both would suit a less-adventurous pallet. One could just make a meal of the warm pretzel bread...yummy! The band is fun, and the decor is great. I love buffets, and so do the kids...you can get your food within minutes of getting seated, and whatever sized portions you like, and can sample a variety of items in one meal, including each dessert Enjoy!
We will never miss Biergarten. The food is fine -- not fantastic, but no one will go hungry and some might even really like it. But, it is FUN!!!!! It is cool and dark and not crowded and they have lots of BEER! And the band is great IF you get in to it!!! My kids think it is the most fun!! They get to run around and dance and and just be silly. No waiting for a photo-op with a character. Just dancing and being goofy. We have been there at high season and low season. Both times, the dance floor was nice and open and the buffet was well-stocked. Definitely go!! If you have a big party, it will be even more fun.
Oh, and did I mention that they have good beer??
