The Historische Wurstkuchl — Historic Sausage Kitchen — is the most atmospheric place to eat in Regensburg and arguably in all of Bavaria. The building sits directly under the Stone Bridge on the north bank of the Danube, in a space so small that the cooking happens in full view of the diners on benches outside. The speciality has not changed in centuries: small, thin Regensburg sausages grilled over beechwood, served six or twelve at a time with sweet mustard and sauerkraut.
The queue is often long, particularly at weekends, but it moves quickly. The sausages cost very little, the beer is cold, and the view across the Danube to the old town skyline is magnificent. Arrive early if you want a table on the riverside terrace — it fills up fast on warm evenings. This is not a tourist trap despite its fame; locals eat here too, and have done for generations.
