San Francisco is a unique city, much loved by visitors, who return frequently to take in the myriad pleasures of the 'city by the bay' With more than 3,500 restaurants and drinking establishments and an estimated 30,000-plus hotel rooms, visitors are in tourist paradise. Arguable the most attractive of American cities and regularly voted the best city in the USA, San Francisco is adored because of its colourful history, dramatic setting and its laissez-faire atmosphere, a quality missing from synthetic Los Angeles.
