I am sure it's pretty high on your list to hit a beergarden once or twice ;) Well, instead of going to Hofbräuhaus (so touristy) you should check out this beergarten, which is supposedly the biggest with 8,000 seats. It's tucked away within the Hirschgarten and has some deers (=Hirsch) right next to it. Get some beer, brezel, fish on the stick, etc. and enjoy!
