The Champagne Sunday brunch (B3,040) at Plaza Athenee (61 Wireless Rd., 02-650-8800) just got a molecular twist. In addition to their foie gras, Swiss raclette, Maine lobster and more, they’re now doing molecular gastronomy-touched small plates and drinks that will be brought around to each table. And for every two people, there will be a complimentary bottle of non-vintage Laurent Perrier Brut Champagne. B3,040 per person.
