I really liked Hairy Goat's photography walking tour of The City area in London (the "mystery tour"). It was great for street photography (Monday during lunch hour in the financial district) and city scape / architectural photography). My guide, Steven - a professional photography - was very knowledgeable about the history of the City and an engaging person generally. He took us to really cool hidden gems through alleys that one wouldn't expect to lead anywhere - Charles Dicken's favorite pub, Shakespeare's church, a garden courtyard with office workers eating lunch in the sun while a guy practiced advanced yoga on the lawn, the shell of a church bombed out in WWII. There is so much to see in The City that I would definitely take this tour again. read more
