Hmm... Well I actually had some difficulty finding decent beats in Muenchen, theres quite a few clubs but most I went to played pretty shoddy music. Harryklein I hear is the place to be, though it doesnt seem to be a well known club. I never made it there, however I did make it to a festival they organise which is awesome. If you can check out Shining Festival (www.shining-festival.de) its this party they throw in this beautiful palacelike townhall at the foot of the alps next to a lake, about an hour out of town. Its a 2 or 3 day party where you camp beside the building. Beautiful location, some of Europes best dj's, beautiful people. Definately a highlight. Also when I went there I was the only non German or Austrian, so that always adds to the charm. almost 9 years ago
In terms of a restaurant/pub you absolutely cannot go to Muenchen without visiting the Hoffbrauhaus!
OK, its a little touristy, but not too much, the locals all still have their own reserved tables. The food is very hearty and you can only buy beer by the liter. almost 9 years ago
