It's interesting to see an outside perspective on a place you're so familiar with. One point that was pretty funny was the idea that London is pedestrian friendly with all those little streets to walk along. I think it's more down to London being haphazardly constructed over the last ~2000 years, and even when it all burned down they refused to change the layout. Which does make it fun. You don't get the line of sight you find in other European cities, and you can twist and turn around the place to your heart's delight.
