Four days solo in London coming up.
Have nothing planned except a concert at O2 arena on the last night and probably going to Royal observatory on Day 2 (flexible on the day)
Like: History, scenery, feeling the local vibe, art, nature, unique food, museums, seeing the view from the top of tall buildings, cool bars
Dislike: Shopping, crowds, touristy things
Take it or Leave it: Fancy restaurants
Staying in Chinatown
You all are always spot-on with advice. What can you suggest?
