The Open Kitchen has prepared a sumptuous dinner buffet for the moms. The menu includes oysters and fresh seafood, sushi and sashimi, cold cuts, foie gras and a carving station, beefed up by a bevy of local delights and a desserts table just laden with pastries and sweets of every persuasion. Mothers will enjoy 50 percent off their bill and receive a complimentary drink from the drink list for a table of three or more diners.
