Maze, a new restaurant in Grosvenor Square, is the latest addition to Ramsay's ever-expanding restaurant empire, and a very fine one it is, too. The head chef, Jason Atherton, is the only cook in Britain to be formally trained by Ferran Adria, the culinary genius behind Spain's legendary El Bulli, and the menu reflects this, offering such imaginative delicacies as sweetcorn sorbet, Sarawak pepper jelly, and sea salt and almond ice cream. Outside of the Fat Duck at Bray, Maze must boast the most innovative restaurant fare in Britain.
