Had some stunning view over east London, including the Thames Barrier, and the many sites for the upcoming Olympic Games, due in a couple of weeks. My only complaint was that the trip was over all too quickly - about 5 minutes. Had to queue for about half an hour - and looking at the queue in the 4th image (from the top), it had lengthened after me ... is the service becoming a tourist attraction already ? Next time I'll try going from north to south.
