I've been to this restaurant twice. The first time was good enough to warrant a second trip, but it's unlikely I'll make a third. Most recently I went on a Saturday night. The server informed us that only two beers were available on tap and the others were bottled, which considering the restaurant is at the brewery reflects poorly on the way the place is managed.
Incredibly loud music that sounded like top 40 country radio played over the speakers, which isn't the sort of atmosphere I want if I'm going to a German style brew pub. My saurbraten was very tough. The pretzel appetizers were OK but were typical chain style food and overpriced for the quality. The server didn't inquire how anything was and generally seemed annoyed to be there. The beer is available elsewhere and the service, atmosphere, and food were mediocre at best. I see no reason to go back.
