LONG BEACH. Remember those glamorous dining room scenes in old movies, where everyone dressed for dinner, and suave men and beautifully dressed ladies chatted over cocktails and waltzed between courses? That is exactly the kind of experience you can have at the Sky Room. After pre-dinner cocktails, the perfect starter course is a foie gras torchon with fig marmalade, brioche, and seared frog legs. Follow with an elegant entrée, perhaps Muscovy duck breast with figs and a crisp polenta cake, or Cote de Boeuf with roasted potatoes and artichokes. For the full experience, dessert is a must ­ white chocolate cheesecake with strawberry compote and chocolate almond soufflé are equally superb. Through the week, a pianist plays classic favorites, while a seven-piece orchestra provides the music on Saturday nights.
