I found this in my search …. It is on my list of “must do’s”

With an encyclopedic assortment of luxury brands, this Knightsbridge institution has more than 300 departments and 20 restaurants, all spread over 1 million square feet on a 5-acre site. If you approach Harrods as a tourist attraction rather than as a fashion hunting ground, you won’t be disappointed. Focus on the spectacular food halls, the huge ground-floor perfumery, the revamped toy and technology departments, the excellent Urban Retreat spa, and the Vegas-like Egyptian Room. At the bottom of the nearby Egyptian escalator, there’s a bronze statue depicting the late Princess Diana and Dodi Fayed, son of the former owner, dancing beneath the wings of an albatross. Nevertheless, standards of taste are enforced with a customer dress code (no shorts, ripped jeans, or flip-flops). Be prepared to brave the crowds (avoid visiting on a Saturday if you can), and be prepared to pay if you want to use the bathroom on some floors(!). http://www.harrods.com. Tube: Knightsbridge.
