Inside the Mandarin Oriental Mayfair hotel, you'll find this top-drawer Korean restaurant. There's only one sitting, so wait for your fellow guests to arrive before taking your place at the handsome marble counter, where you can relax and enjoy the sight of the chefs working quietly and harmoniously in front of you. Names like kimchi, bibimbap and bingsoo may now be familiar to many, but the dishes that make up the poised and beautifully balanced set menu here are explained in great detail. Much of the produce is British, such as Orkney scallops, Dorset crab and Dover sole.
