I've experienced the Bier Markt a few times and let me tell you, it isn't a place to come for good beer. They have beer...a lot of it, but most is macro and pseudo-micro beer. There are some craft beers, but not many considering the vast beer menu.
My latest visit was on a Saturday night and the line up was very long and inside was packed full. This appears to be a good place to come get drunk and dance to live music, so the naming of the place escapes me.
