Great selection of books and magazine with a big focus on rare. out-of-print books Japanese photography. Can sends hours in this little shop. I'd try to avoid on Market day (Saturday) if you want to have a good look as it can get a bit busy for such a small space.

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.

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

Outside of the major players (Tate, V&A, RA) this is probably the best programmed gallery in London

best family run sushi i can find in London.  Not flashy but that not the point.  Its a small honest run place.  Its great.
