'Table seven calling number four....' Berlin's retro chat-up lines
This is what phone-flirting looked like long before the existence of dating apps: numbered telephones on nightclub tables enabling smooth-talking calls to whoever caught your eye.
Once all the rage in Berlin's Weimar-era clubs and ballrooms, incredibly, these pioneers of the pick-up line still exist in the Ballhaus Berlin, a century-old dance-hall in the heart of the city.

Don't be fooled by the building's unprepossessing exterior - inside (to steal a phrase from 'Cabaret', which also features its very own table-telephone song) "life is beautiful". Or at least, a rather glitzy confection of gilt, mirrors and a balcony overlooking the dance-floor.
But the star attraction at Ballhaus Berlin is, of course, those late 1930s 'Tischtelefonen'; a unique survivor of the city's racy pre-war heyday. Get ready to flirt, retro-style, because for once, an inability to put down your phone is all just part of the party.
