I probably spend too much time here but I love it for the atmosphere. During the day it’s quite empty. The proprietor is often dozing in the back corner and you can read for hours with just one cup of tea without anyone bothering you. It picks up in the evenings as all the regulars pile in with pre-bought bottles of wine.
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.
A beautiful and spacious (outside of rush hour) way to get from Highbury, through east London to south of the river in minutes. The train snakes epically through Hoxton and Shoreditch and opens up the Jubilee Line via the beautiful Canada Water / Bermondsey stations.
