This beach club–restaurant–lounge–jazz club is the most romantic and sophisticated dining spot on the beach. By day, you can lounge by the pool or surf between bites of ceviche, panini, burgers, or mussels with fries. By night, you'll find tables set with white linens and candles arranged under swaying palms around two glowing pools, while the sound of waves breaking on the beach blends with the very cool soft jazz (live on Friday). Start with a lobster and mango salad or a flaky pastry nest filled with goat cheese and spinach. Move on to a divine fillet of sole bathed in a velvety, peppery champagne-cream sauce. The ahi tuna is almost too beautiful to eat, topped with arugula and caviar on a tower of thin and crispy potatoes. There's a good wine list and light, refreshing Argentinian wines by the glass. For dessert, try the crêpe suzette flambé. Come back the next day to work off your meal at the attached fitness center or yoga studio.
