Probably my favourite building in the city, and right in the heart of it. There are always interesting events happening here, across art and music, and you can drink in the courtyard during summer
There are not many places in London like it. On a Saturday during market hours it heaves with stalls and visitors for a good mile or two. Great place to pick up some bric-a-brac, genuine oddities and a great bite to eat, or just enjoy the hustle and bustle vibe of the place.
