Down by a graffiti-strewn stretch of the Danube, Flex might attract a very young and mainstream crowd today but still manages a semblance of its one-time edginess. The sound system is rumoured to be one of Europe's best, entry prices are usually reasonable and dress code unheard of. Local and international DJs are joined by occasional live acts.
Nights vary wildly from hardcore drum and bass to indie or electronic (for which the club is best known). In summer, the Flex Cafe (no cover charge) has picnic tables lining the canal, which overflow with happy drinkers, and its own, slightly more subdued, dance floor.
