3.5, but rounding up for a nice little salad bar to start off your meal. I've generally found…read morevegetables (aside from potatoes) fairly sparse on menus in Germany, so having a small salad to start my meal was a nice touch. There isn't a massive selection, but everything there was fresh and tasty.
Beer selection was solid, as to be expected, and the food was all good. The schnitzel was nice and crispy on the outside, and still moist enough on the inside. The burgers looked decent enough, as did the grilled pork with spaetzle.
Service was typical for Germany, and as you'll find in a lot of places the food comes out of the kitchen as it is ready, not all at once, so there can be some time between the first and last plates arriving. If that is the case, the polite thing to do in Germany is to eat your food when it arrives so that you are eating it hot.
