There’s something about the London Underground, that like moths to a flame, day in, day out, we find ourselves drawn to. This subterranean network unearths the real sights of London – avant garde hipsters, browbeaten bankers, erratic octogenarians and clusters of excited tourists. This is where you’ll begin to understand the eccentricities of our capital's eight million residents. Rent a pop-up shop inside the transport system and you’ll be well placed to attract the diverse crowds that are guaranteed all day, every day.
