Fodor's Expert Review Berghain

In an imposing power station in a barren stretch of land between Kreuzberg and Friedrichshain (the name borrows from both neighborhoods), Berghain has achieved international fame as the hedonistic heart of techno music—it was originally a 1990s techno club called Ostgut. It's only open as a club on weekends (for 48-plus hours straight, from midnight on Friday to early Monday), though many international music acts pass through for concert performances during the week. It's become something of a local tradition to arrive on Sunday morning or afternoon and dance until closing. Upstairs, the slightly smaller (but by no means intimate) Panorama Bar opens on Friday at midnight and offers different beats.
