Having been to the Munich Hofbräuhaus, it's hard to compare. The atmosphere and décor is spot on. The servers are dressed appropriately. The live music is the right instrumentation, but not sure they play songs from the Sound of Music in Munich. It's almost Americanized German music. He was also a little loud for the number of people there for lunch, which wasn't very many. If the place if packed, I'm sure it wouldn't have echoed that much.
In typical German fashion, there are NO substitutions! Therefore, we ordered a mix of dishes in which we obtained everything we wanted. However, the food ended up just being OK. Nothing special to write home to Germany about.
Overall we had a good experience though. For someone who has never been to Germany, or isn't planning on going, this is definitely worth the visit.
