If you are going to China Town then if your kids enjoy video games, take them to gamerbase which is inside HMV in Piccadilly Circus. At the back of the store they have consoles and PCs to play games, less than a tenner for them to play for the afternoon. I left my kids there for a couple of hours while catching my breath in starbucks! I think they have to be over 12 years though.

Not free, but you could try some brass rubbing in the Crypt at St Martins in the Fields.

Don't forget to go past Household Cavalry Museum on Whitehall, where they can see a soldier standing sentry (possibly horses too).

Which part of South London are you staying? Because there is life outside of central London too!
