The walk along the South Bank from Westminster to Tower Bridge will take you past a plethora or interesting sights and cultural hotspots. There's always something interesting going on too.
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.
A friend took me to this bar on Greek Street, I’m unsure of what it’s called or if it should be there, but it feels pretty authentic and makes you dream of the Soho of the 60s.
