A great walk down an old abandoned rail way from Finsbury Park to Highgate. Most of the original platforms are sill remaining so its an interesting place to explore...
It is one of the most important business centres in London. Crowded of suits at daytime, perfectly deserted at night. It is so striking relaxing to walk in there enjoying the silence and the lights! It makes you feel pleasantly far from reality.
Just down the road from where I live is this Art Deco cinema where mainly locals go. Watching films and sitting in this old theatre really adds another level to the experience.
