Visit London and you'll never be short of things to see and do. From Tower Bridge to the Houses of Parliament, a simple stroll along the river Thames will allow you to take in some of the most famous buildings, galleries and attractions in the world.
According to the UK Office for National Statistics, London is one of the most visited cities on the planet, with nearly five million holidayers flocking there from abroad between July and September in 2013 alone (and almost all of them stopping for a selfie outside Buckingham Palace...) For the first time visitor, there are plenty of informative guides on offer and many a well-worn, well-signposted tourist trail to follow covering all the major attractions.
But what if you've already been there, done that and bought the plush, oversized Union Flag top hat? Or what if you just want to escape the hoards and explore the more eccentric side of London off the beaten track? London is full of unique things to do that don't necessarily make it into your average guidebook.
You might have to look beyond Trip Advisor to find them but - thankfully - Londoners take such pride in being the first to reveal the latest secret scenes, sights and sounds that there are host of hidden gems to be discovered via blogs, social media and a good old fashioned stroll around. From the '90s Brit Pop singing ticket barrier at Canary Wharf to Sherlock's favourite eatery, we've rounded up 15 of the best alternative destinations to get you started...
