This may not be much of a secret but deserves a mention. I find it hard to go anywhere near this place without having to go there. Freshly baked Beigels hot salt beef and it never closes, 24 hours a day 7 days a week.
An unassuming glass door on an otherwise plain facade hides a cavernous space, with high ceilings and huge sliding partitioned walls producing excellent exhibitions in a space you'll want to go back to.
This is a little general but there’s so many great cinemas in London, I can’t choose just one. I probably go to Screen on the Green most often as it’s nearby and shows great films, has really comfortable armchairs and serve drinks to your seat as well as hosting director Q&As and late night screenings. Other favourites include: Curzon Mayfair, Renoir, NFT, Barbican and Prince Charles cinema where I’ve been to a great Movie Maths triple bill; RoboCop + The Raid = Dredd. I can’t get rid of anything so compile all my tickets in a file chronologically, which also serves as a map of where I was living at any one time; depending on which cinemas I frequented the most.
SOAS university has a small gallery space dedicated to exhibitions about Asia, Africa and the Middle East. There's a small but beautiful Japanese zen garden on the rooftop (currently closed for refurbishment)
