"Basque food may not be what you think of when you think of Mexico, but Danubio absolutely deserves a visit. It’s been open for more than 85 years, and I don’t think it has changed at all, right down to the way the waiters are dressed—here it’s as if time had stopped. The langoustines a la plancha, grilled and served simply with garlic sauce, are a must." - BySantiago Pérez, as told to Amiel Stanek
