The most beautiful contemporary gallery in London aptly named White Cube, the space is an artwork in itself. Its portfolio of artists and exhibition programme is top of the league, always presented as with style and grace as the space itself. Photograph by Paul Riddle

This is a great, free and lesser known spot in London. A glass lift takes you up the side of st.Paul's cathedral right out onto the roof terrace of this shopping centre. A great view over London.

Great night walks.

Museum exploring connections between medicine, life and art. Fascinating range of exhibitions and great shop, library and cafe. Free entry too. 

Just above the Dorfman Theatre lobby at the National Theatre, is the entrance to the high-level walkway, a public walkway that overlooks the National Theatre props and scenic workshop. It's free and is a unique chance to get a glimpse of what happens backstage. I love popping in when I'm on the south bank, as you get a completely different sight each time, depending on which production the workshops are working on at the time.
