Marks & Spencer, London

Affectionately known as Marks & Sparks, this is undoubtedly a British shopping institution. There can't be a single man, woman or child in the UK who doesn't own something from M&S, especially from their famous underwear selection. The appeal of the chain lies in its conservative approach combined with quality and value. While critics have pointed out that M&S has been slow to absorb new trends, they have responded by hiring younger and hipper designers like Julien Macdonald and Katharine Hamnett to create exclusive collections. The new Autograph section within selected stores is their answer to designer/boutique shopping. Quality and convenience foods are also a strong point. Branches nationwide and overseas.
