Don’t expect faded Victoriana, over 300 years the building has evolved from Victorian sailors' pub to music hall, Methodist Mission to rag warehouse, eventually falling derelict before reopening as the venue it is today.
Follow the light to the end of the alley, (not an instruction I’d give in all parts of London’s East End, it never did any of Jack the Ripper’s victims any good) but this is worth it.
Stop under the huge street lamp and push open the door. You are transported into the world's oldest surviving Grand Music Hall and immediately enveloped in its intimate, albeit elegantly crumbling (Financial Times) atmosphere.
