Michelin-starred Nahm was the first Thai restaurant in Europe to be so decorated, and the cuisine is as impeccably sophisticated as you would expect. Overseen by award-winning head chef David Thompson, the menu is based on ancient Royal Thai traditions, and the authenticity even extends to the serving style (all in one go in the middle of the table). A short walk from the shops of Knightsbridge, this beautifully chic restaurant also offers lunchtime diners a menu inspired by Thai street food.
