In Vienna, this name has nothing to do with George Gershwin's musical. Here it is actually the best jazz club in town. Its array of performers from Europe and around the world is absolutely first class. Established in 1993, the club became an instant hit and has been going strong ever since, patronized by Vienna's most avid jazz aficionados. It also often hosts popular world-music groups, singer-songwriters, and international touring greats of the jazz scene. The club has shows almost every evening and closing times vary, often 3am or 4am.
