"A nondescript shopping arcade in a tony neighborhood might not be the place you'd expect to find one of the world's top restaurants—but if there's any place that reinforces the adage about not judging a book by its cover, it's Mexico City . Biko has been ranked on the World's 50 Best Restaurants list for years now. The two executive chefs aren't as visible as other local chefs on the list, but that may be because they're constantly in the kitchen, turning out memorable dishes. Guests can order off one of two menus: one is more traditional-inspired Basque cuisine, while the other is contemporary. Expect playful presentation and exceptional service."
