We went last March for the first time and enjoyed it. It was a last minute choice and we had no idea what to expect.
We had dinner, which is a buffet. There was really good chicken, sausages, potatoes, scnitzel and other stuff. Lots of choices, including salad. I liked the apple strudel for dessert.
When you walk in the restaurant, there is seating on a few levels and in the back it looks like a street scene with brownstone-looking buildings as they would appear in Germany. There is a stage where musicians play. One part of the act is people ringing bells. The German band also plays these long horns, I can't remember their name. There is singing and they encourage the crowd to sing along too.
My husband definitely wants to do it again because he liked it so much. I would go back as well, but there are also other places we haven't tried yet that I want to get to.
Give it a try - it was fun and different.
