DH and I had lunch there on our last trip. Good food.
I don't eat pork, or any kind of sausages, but I still had plenty of good food with the chicken, the side dishes, salads, and (especially) the spaetzel. This was only the 2nd time in my life that I have ever had German food, and I enjoyed it.
DH's late grandmother was German, and he had a lot of the German foods as a child, so he liked trying them again. I don't know how "authentic" they are, but DH probably doesn't remember a whole lot about what he was served by his grandmother, as she died when he was young. He remembered the names, the images, and some of the tastes, and he was glad to re-experience some of them.
