"I'd have to say that St Martin's Lane, behind Trafalgar Square, is one of those small streets that many wouldn't notice unless by accident or if suggested by someone else. It is a small street with extensive options, such as theatres, cafes and second-hand bookshops. It's wonderful how such a narrow, relatively quiet street is home to all these things! The best part is, you don't have a lot of street traffic, as is mostly typical in other London locations, and you can buy yourself a book, go to a neighbouring cafe and enjoy your time reading or chatting with friends."- Christina
