"Chef Fernando Rivarola ventures across Argentina to source ingredients from artisan producers, and pays special attention to exotic meats like llama, alligator, and river fish. The chef, along with his wife and sommelier Gabriela Lafuente, organize a pop-up series called Cocinas Sin Fronteras, or Cooking Without Borders), and invite notable chefs from around the world to cook in Buenos Aires." - Allie Lazar
