Is there somewhere maybe interesting you could suggest which is also outside tourist lands or
Shoreditch, the adult playground.
Richmond, the happiest place in the UK
Walthamstow, the most multi-cultural place you will ever see.
Interesting thing to do is to go on buses that cut through the suburbs across the underground lines as the closer people are to major transport the wealthier they are...there are great swathes of London that are like little worlds to themselves and are highly segregated in various ways.
