The Hofbrauhaus can provide a "guten nacht" for everyone if you want to go to a great German themed restaurant. However, expect to pay for it!
Having been to the actual Munchen Hofbrauhaus and I can tell you the decor is quite similar. Big long oak tables, a boisterous band of German singers, and more beer than you should be drinking.
The food while not absolutely authentic "best German food ever", I do think that it provides enough of an idea of what German food looks and tastes like for the curious patron.
This particular night that I went, the "haus" had a really fun young band of German singers who really knew how to get the crowd into the night. There was drinking songs, blowing the alpine horn game, and drunken dancing. What else do you want from a German restaurant?
The one problem with Hofbrauhaus is the fact that its more like a "tourist spot". You just go there not for the food, but for the experience and the "I just went to Germany feeling". While I recommend everyone to go once. Going on a regular basis probably means you don't care about money, or you're an alcoholic.
Try it once, order the Leiberkase (don't ask me what it is) and enjoy!
