I would say that this is a unique landmark of London. It gives you the chance to enjoy the magnificent view of the whole city of London. Be prepared to have to wait in line for long time. It costs around 30 which is not by any means cheap but the experience is very rewarding. It takes about half an hour to complete a full circle and the maximum height is around 135 m.
