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 blingtastic tourist attraction rather than as a center of elegant sophistication, 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. Nevertheless, standards of taste are enforced with a customer dress code (no shorts, ripped jeans, or flip-flops). Be prepared to brave the crowds, especially on weekends.
