Everyone should visit this absurd restaurant once in their lifetime. Its over-priced, mediocre food but the decor and ambiance is like nothing else in theatrics and campery. You are met on arrival by a white velour 'napkin' artfully screwed up on your diner plate. Absorbent, not? Fabulously awful, yes.
It's really close to my house and one of my favourite pubs in London! (I even went before it was close to where I lived!) It is London's first cooperatively owned pubs and has lovely events and workshops, exercise classes and great parties, and good beer! It's lovely in the beer garden in the hot summer and equally great in the winter, next to a real fire.
It is an independent arts organisation in Elephant and Castle. It is one of the best venue for electronic music in London. On Tuesdays Boiler Room, best DJs for free with guest list.
This may not be much of a secret but deserves a mention. I find it hard to go anywhere near this place without having to go there. Freshly baked Beigels hot salt beef and it never closes, 24 hours a day 7 days a week.
