You haven’t really ‘done’ Berlin unless you’ve emerged sweating and squinting into the sunlight from an all-night weekend dance party. The beats are relentless, the action doesn’t get started until almost dawn, and the stamina required seems way beyond what the unadulterated body can muster. Try the perennials Tresor or Panorama/Berghain, or one of the roving affairs in any of the hundreds of bizarre and fascinating post-industrial spaces around Berlin.
