The Global Food Kitchen at Camden Lock Market in London is famous not only for good eats but for its shops and stalls—more than 200. No wonder it attracts 6 million visitors a year and is the hub of the growing street food movement here.
London's East End famously was home to immigrants for centuries—French, Irish, Jewish, and most recently Indian (the famous Brick Lane lined with Indian curry restaurants is here). There are also hipsters and artists -- the area is as famous for its street art and pop up shops these days.
The Rubens at the Palace and Egerton House hotels in London offer families an upscale experience. The kids are treated like the royalty that live across the street from the Rubens.
