Aside from the fact of the underground being the oldest running railway system in the world, I find the underground just an incredibly strange place. Sometimes it’s like I’ve entered an organised maze and just walk without even thinking. The photo is taken of the floor from one of the trains, it’s normally what you tend you look at when you’re on the train.

An obvious choice but no 'best of London' list is complete without the Barbican

Walthamstow Wetlands are London's largest urban wetland nature reserve, home to many wildlife species. Only 15min from central London. The cafe is open daily for breakfast, lunch and afternoon tea. 

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.

Maybe an obvious choice, but the Barbican is always good. My favourite space in there is the curve gallery, last time I went was for Cory Arcangel's 'Beat the Champ'. I love the architecture, although not many people do. I think it was voted 'London's ugliest building' in 2003.
