Lee,
I've been to Hofbrauhaus more than once because people I'm traveling with always feel they "need" to go there.
Too often, the tables are populated by groups that look like they just got off a big bus. They take non-stop pictures of everything and each other. I have to admit they are usually in a festive mood.
I've also gotten the impression that locals sit in one area while tourists are confined to another. Maybe that was just an impression but it's the only time I ever went to sit at a community table and was told not to sit there (they were German and weren't waiting for the rest of their party).
As you said, the waiters speak English rather than German.
The music and look of the place are similar to other bier hauses but the environment isn't local at all.
Busch Gardens Williamsburg looks like Bavaria but is really just a tourist attraction. Hofbrauhaus is the same.
Go to another bier haus. Enjoy the same music, better beer and warmer treatment from the staff and patrons.
