What is "foyles"

W & G Foyle Ltd. (usually called simply Foyles) is a chain of book shops with seven locations but is best known for its flagship store in Charing Cross Road, London. Foyles was once listed in the Guinness Book of Records as the world's largest bookshop in terms of shelf area (30 miles/50 kilometres) and number of titles on display. In the past, it was famed for its anachronistic, eccentric and sometimes infuriating business practices; so much so that it was a tourist attraction. It has since modernised, opened new branches and established an on-line store.
