To mark the Thai New Year, Bill Marinelli’s oyster and seafood restaurant The Seafood Bar (Somerset Lake Point, 41 Sukhumvit Soi 16, 02-212-4809) is doing an oysters and Champagne promotion for the entire month of April. For B990, you can get a dozen fresh or cooked oysters and not one but two glasses of Champagne from Domaine Chandon.
