Not the most exciting place inside, but a lovely rooftop area which not all that many people seem to know about, 2 mins walk from Old St station. If it’s packed then The Red Lion is just up the road.
This is the most genuine and unpretentious pub I have visited in London. The Palm Tree is on the east London canal outside of Victoria Park. You won't find it unless you know it's there. (And now you know!)
Regeneration or gentrification? Having been living in and around Brixton for almost two decades, I'm not the only one witnessing its gradual transformation. Right now, Brixton offers an intriguing mix of Jamaican and British culture like nowhere else.
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.
