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.
The walk along the South Bank from Westminster to Tower Bridge will take you past a plethora or interesting sights and cultural hotspots. There's always something interesting going on too.
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.
