With views through gnarled and ancient olive trees over the beach into the Mediterranean, this sleek spot hidden "under the boardwalk" near Frank Gehry's gleaming goldfish may not be classical Barceloneta in decor or cuisine, but it's an exciting place to dine. Hit the terrace on warm summer nights and sunny winter days, or just catch rays inside the immense bay windows. Seafood is the main draw, but rice dishes, beef, and lamb are also equally available. Expect action, bustle, streamlined design surroundings, beautiful people, elevated prices, and good-if-not-spectacular fare at this very popular tourist favorite. Be sure to reserve in advance.
