London's crème de la crème flock to French virtuoso Hélène Darroze's restaurant at the Connaught for her dazzling regional French haute cuisine, served up in a sexy Edwardian dark-wood-paneled dining salon tricked out by Parisian It-designer India Mahdavi with geometric carpets and high-backed comfy chairs. Taking inspiration from Les Landes in southwestern France, Darroze sallies forth with a procession of magnifique dishes, like local Robert Dupérier foie gras with cardamom and sorrel or Limousin sweetbreads with girolles and Jerusalem artichokes. Spit-roasted and flambéed Racan pigeon is served gloriously pink and Pyrenean lamb is served en rognonade (with its kidneys). To finish, choose poached yellow peach from Provence with gingerbread cream. Darroze is perfect for a splurge, but beware the high prices: £38 for lunch, £55 for brunch, and £92–£155 for set dinner.
