Peru’s Gastón Acurio is Latin America's biggest celebrity chef. Along with his wife, Astrid, he has held a spot atop the Santiago food scene for more than a decade. Expect flawless service, elegant ambiance, and seasonal tasting menus with at least half a dozen fish options (often combined with other seafood), as well as beef, and a nightly tasting menu of the chef's favorites. Advance reservations are a must. It's expensive but if you're on a budget you can still come in for a ceviche and pisco sour at the bar.
