I've been to London on business several times (five?), and have rarely had time to just SOAK in it. So, as my third city to meet my third friend, pre-Brexit London seemed like a fantastic choice.
Ultimately, she didn't come, but I had a great time, in a mix of hot-to-rainy weather, mostly indoors.
The UK (or at least the British element of it) brings to mind images of tea and teacups, the Queen, British New Wave bands (I can finally visit without having ABC's Tower of London, the Clash's London Calling, or the Smith's Hairdresser on Fire on endless loop in my head), and various other icons from an earlier era.
Yet, London is an extremely modern, international city, and so I focused this trip on experiencing ultra-modern things: contemporary art by living artists (Studio Olafur Eliasson, whose work is always so fantastic, have a show at the Tate Modern!! YES, I did plan around this!) , design award shows focused on making the quality of life better for us, and on the constructs that AI systems create, and street art.
There are so many flavors of London to experience!
