Sacred, 13 Ganton St, off Carnaby St. (Oxford Circus)

This bustling shopping area, with its associations with the swinging sixties London, is likely to be an expensive place for a decent coffee. Luckily, Sacred make a pretty decent cup. They also have some tables inside and outside that let you watch the (very fashionable) world go by, and there is no traffic to worry about.
