While you are in London, you will most likely end up using the tube. You will see that there is the normal service area and then the extended area. in the extended area is Camden Town, might not be your cup of tea but there are some good clubs, pubs and interesting little shops. There was a fire there a few years back so I don't know what made it through. There are some places you want to avoid, and it will be pretty obvious you don't belong. Bullox to everyone that says the UK doesn't have good food. Pub food rocks, hunters chicken especially, also if you like Thai food there is usually a lot of that to be found.
