Greek cuisine is rooted in simplicity and quality ingredients. At Estiatorio Milos in South Beach, there's something new to discover on every visit: The fish selection changes daily depending upon what fishermen haul in. The day's catch is prepared to your liking and priced according to weight. There's nothing newfangled here, but when it comes to topnotch seafood, Milos is in a league of its own. One of the restaurant's specialties is melt-in-your-mouth charcoal-broiled octopus, seasoned with white balsamic vinegar and olive oil produced by the owner's sister in Greece. Another signature dish is the tomato salad, with cucumbers, green peppers, onions, kalamata olives, and feta cheese. The restaurant's homemade Greek yogurt dessert is so thick and creamy you'll never believe you're eating something that's good for you.
