South London is largely underrated considering at times it's a treasure chest of gems; Battersea Park is one of those big sparkly ones. An interesting mix of faultlessly pruned gardens, displaced architecture, shape, form and colour generate a delightfully influential weekend stroll. With views of the almighty Battersea Power Station and the river dividing you from the Chelsea Embankment.
Hotter than hell, but always a good night had. It can be whatever you want it to be - restaurant, pub, or club, has good outside space and rentable rooms, and plays an interesting mix of music to an interesting mix of people. The building is actually kinda beautiful too.
London is so vast I end up spending hours travelling on trains. They are by far the best way to travel around on and are always full of weird and wonderful characters.
I love the architecture of the Barbican - it is so important to its historical context, at a time when London was being shaped for modernity after the war - they also aspired to make it a bold art centre. We need bold, always.
