This bar is an attraction on its own. Both tourists and locals come here for a few beers so it can be crowded but the place and environment is nice nevertheless. The beer was made by themselves and tasted pretty good.
When you reach Markplatz, the town square, you are awed by the Rathaus, St. Petri Dome and all the lovely buildings facing the square. But please do explore the back streets. There are interesting places and restaurants. Of not, Schuttinger, the hidden bar, Bottstruasse, the oldest bar in Bremen, etc
