The Haufbrauhaus only serves 1 Liter mugs of beer. This short, stout German barmaid carried out 7 of these mugs in one hand!!! The beer is amazingly good because it has no preservatives. I did finish my mug of beer!! The regulars have the official HB (Hofbrauhaus) steins which are a ceremaic gray with a royal blue HB on the front. They keep them hanging in little locked cabinets in the back of the beer hall.
