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.

Bordering the west side of Victoria Park, Regent's Canal serves as a pleasant walking or riding track, particularly on weekends when it's at it's quietest.
Quinto sells second-hand books. I spend a lot of time here and have found some inspiring books over the years, both at Quinto and the other shops on this road. Koenig Books on the corner is good for art books, too.
The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.
