San Francisco, California
There is a distinctly European air about San Francisco, partly because of its higgledy-piggledy housing and lack of an obvious grid system for the streets. The hippy era drew many Brits and established its latter-day reputation as a sophisticated city. Go to You Say Tomato or the Pig and Whistle for English accents mixed with the iconic British products, but San Francisco goes one step further. For the last few years the local immigrants have taken to the beach and organized a Guy Fawkes bonfire night on November 5, the time when Brits do their firework thing.
