LONDON, Aug. 8 -- Zsofia Csaba, a waitress at the Sanctuary pub, rode the subway to work every day until July 7, the day bombs exploded on three Underground trains and a bus, changing the rhythm of her life and her city. Since then, she has ridden a bike, preferring not to use a transit system where 52 passengers and four presumed bombers perished and 700 people were injured.
