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.
I grew up around this area - it really is a gem of a place. The interior is so cool, with sort of organised clutter everywhere. They have a little garden and they serve food. Its not the best in the world, but the whole experience there is great.
As preposterous as this sounds I think there are few ills that can’t be cured by sitting lazily on a stack of rugs in Liberty and allowing the patterns to wash over you in a warm, and slightly itchy, haze. If you don’t believe me try it. The second you step off the main shopping area the sound and lights dim, the rugs beg to be touched, and all your worries seem to disappear.
The Hayward Gallery in Southbank center has held my favourite exhibitions in London and each time they are extremely well curated. Definitely a place to visit !
