Most bars close between 2 am and 4 am. Nightclubs typically charge entrance fees ranging from €5 to €20. In addition, some trendy places, such as King Kamehameha, enforce dress codes—usually no jeans, sneakers, shorts, or khaki pants admitted.
Sachsenhausen (Frankfurt's "Left Bank") is a good place for bars, clubs, and traditional Apfelwein taverns. The fashionable Nordend has an almost equal number of bars and clubs but fewer tourists. Frankfurt was a real pioneer in the German jazz scene, and also has done much for the development of techno music. Jazz musicians make the rounds from smoky backstreet cafés all the way to the Old Opera House, and the local broadcaster Hessischer Rundfunk sponsors the German Jazz Festival in fall. The Frankfurter Jazzkeller has been the most noted venue for German jazz fans for decades.
