The short clip from a German city: The caption says: "Mannheim - Germany" but the clip shows a shot of the reconstructed historic center of the city of Hannover in the north of Germany. The bell tower you see is a part of the Marktkirche (market church). Hannover is located some hundred miles northeast of Mannheim. The bar on the left you can see is a wine-house which has definitely nothing to do with the interior shown in subsequent scenes. The interior is obviously a set.
In the background of the bar in Mannheim (Baden-area, Germany), you can see a poster for "Mottsbacher Kölsch". While the fictional brand itself could be used anywhere in Germany, the Kölsch type of beer advertised is almost never sold in bars outside the Rhineland area.
