First he opened the eclectic Nemo at Collins Avenue and First Street in South Beach. Then came the hip Big Pink diner across the street and up the block. Both were huge hits, but Myles Chefetz was just getting started. Next was Shoji Sushi, next door to Nemo, and then, just more than a dozen years ago, he hit the gastronomic grand slam with Prime One Twelve on Ocean Drive, which not only redefined the modern steak house but also has been one of the top-grossing restaurants in the nation for years. To keep the good times flowing, Myles moseyed across the street and premiered Prime Italian — another big, crowded, exciting, expensive restaurant, and another huge success. This year, the restaurant mogul will convert Nemo into Prime Fish, which figures to keep the winning streak going. All of these restaurants are within a block of each other, and all are south of Fifth Street. Chefetz reigns over this neighborhood, but his influence stretches across the entire city. That's likely why he was nominated last year for James Beard Foundation's Outstanding Restaurateur Award. He didn't win, but he gets this Best of Miami award as consolation.
