Harrods       

Harrods in London's Knightsbridge has gone beyond being a mere department store, and has has become a tourist destination in its own right. Tucked away in Knightsbridge, away from the main shopping area, this is the place to come to buy that chic green bag that wraps all purchases made here from a Chelsea bun to a grand piano.
You can spend days wandering the floors. There is the extensive Food Halls on the ground floor,where the rich and the famous get their groceries, the cosmetic counters, a book shop, you name it, they have it.

Perhaps it is a little less exclusive than it was in the days when they had their own fleet of ships scouring the world on behalf of their patrons, but never the less it is a pleasant place to spend a few hours, and you will probably end up the proud owner of one of those green bags
