The original Hofbrauhaus is phenomenal! You have to sit in the main dining room. It's best on the weekend evening when hefeweizen has been flowing for a bit. The food is traditional German fare. From your standard schnitzel to giant pretzels with beer cheese. You really can't go wrong here. Once the music starts playing, the food is served, and the beer is flowing you will soon find yourself pounding a beer on the table yelling "Prost" out loud with the rest of the diners.
You have to experience this place at least once to understand, but it will be so worth it!
