Fodor's Expert Review Altstadt

This party-hearty district has been dubbed "the longest bar in the word" by locals. Narrow alleys thread their way to some 300 bars, clubs, restaurants, and brew houses. All crowd into the 1-square-km (½-square-mile) area between the Rhine and Heinrich-Heine-Allee. When the weather cooperates, the area really does seem like one big sidewalk café.
