Eccentric and surprising house and museum of architect Sir John Soane. Mostly unchanged since his death over 180 years ago, it is full of atmosphere. Also have spotlit, late night openings.
I grew up in Brighton which is full of cheesy bars like this. If you can handle being surrounded by multiple screens playing Kylie at full volume, its pretty much the cheapest bar in central london. The cliental is so varied its great for people watching and completely un pretentious.
The Nightingale is the antithesis of the hundreds of soulless gastropubs that a lot of decent pubs have recently become and remains everything a proper pub should be. Britain's pubs haven't had it easy lately. The smoking ban and the general effects of the recession have hammered the industry hard. The Nightingale continues to be what it has always been, a proper pub at the heart of the local community. Its annual charity walk has raised nearly £500,000 for good causes in over 30 years and it seems determined to do the things a pub should do and do them properly. Once inside you feel like you could be in a country pub instead of in the middle of South London. There's no jukebox and the TV is hardly ever on, but there’s a great atmosphere with a good set of locals and good drink and food. Bliss.
The Hayward Gallery in Southbank center has held my favourite exhibitions in London and each time they are extremely well curated. Definitely a place to visit !
