If, like us, you're something of a coffee nerd, you'll already know about east London's premier roastery and café. It's got a roving coffee stall you'll find at a few food markets and, obviously, a big old roastery in a railway arch – where it roasts single-origin beans, but also holds regular parties and food pop-ups. Climpson's flagship, though, is the excellent café on Hackney's Broadway Market. You'll find it full-to-bursting every Saturday.
