My wife and I will be in Munich next week and are looking for some recommendations for restaurants serving a good meal at a fair price. I am thinking along the lines of $20 each (not including wine). We are staying in the city center right across the street from the Hofbrau Haus, so that will be one meal. Any suggestions? Any little hole-in-the-wall that you know of that is just so unbelievably good you can't imagine why everyone doesn't go there?
