About London
London is expensive, but its free museum collection rivals any city on earth — the British Museum, Natural History Museum, V&A, National Gallery, Tate Modern, and more are all completely free. Add excellent cheap street food from Borough Market to Brick Lane, affordable day trips to Oxford and Stonehenge, and the extraordinary density of history and culture, and London can be done for less than most people think.
