"Enter a Different World", it says on the doormat, and this is what you do when you visit Harrods in Knightsbridge, London. Harrods is "the world's most celebrated store", says Chairman Mr. Mohamed Al Fayed.

Over the years, Harrods has survived a fire, two World Wars and even two bombings. In 198; Harrods moved abroad and opened a branch in Japan and later others in Hong Kong, Singapore an Taiwan, as well as airport shops in most major European cities.

Today around 35000 people visit Harrods every day. It has got 300 departments spread over seven floors and employs over 4000 stuff. It also has eight doormen, known as 'Green Men', as we as its own fire brigade, security personnel, doctors and nurses.

Harrods is the official supplier of certain goods to the Royal Family, and sells everything from clothes to caviar. The Food Halls are still the heart and soul of Harrods. In addition to the nineteen bars and restaurants in the store, there is a bank, a travel agent's, a dry cleaner's and the biggest ha and beauty salon in Europe.

January and July are very busy months for Harrods because they are sale times. Over 3000( customers visit the store on the first day alone. Many people sleep outside the store all night to 1 first in when the doors open on the first day.

"All things, for all people, everywhere" is the store's motto. The Harrods name means the best i British quality, service and style. All in all, Harrods is a fascinating place to visit.
