Remarkable Places to Eat: San Sebastian

Nisha Katona takes Fred Sirieix to San Sebastian for a mind-blowing meal at one of the world's top restaurants and to visit a tiny sports bar to learn the secrets of the perfect tortilla. The first place in Nisha's little black book is Mugaritz, ranked as the ninth best restaurant in the world and famous for wild experimentation - something that is made clear as soon as the menus arrive. Instead of a list of dishes to select, the Mugaritz menu is two pictures, one of a swimming fish, one of a flying fish, and Nisha and Fred make their choice, but have little clue what they are going to eat
