Most German restaurants in the USA specialize in Bavarian food, but Walzwerk specializes in food from the former German Democratic Republic (DDR), a cuisine that's heavy on the meats and high on the calories. Located in San Francisco's Mission District, the restaurant is a hit among the locals. If I ever have a chance to visit San Francisco, I'll give it a try. In Berlin, it would be difficult to find a restaurant of this kind. The city has plenty of restaurants, but very few that offer traditional East German food.
