Restaurant Week, which was supposed to end after Friday night, has been turned into Restaurant Summer, with 130 restaurants extending their prix-fixe deals on weekdays all the way through Labor Day. The special three course menus – $24.07 for lunch and $35.00 for dinner – have proven extra-popular with recession minded diners this month, according to NYC & Company, which organizes the biannual deal. Restaurants participating in the Labor Day extension include such well-reviewed places as Centro Vinoteca, Mai House, Artisanal, Le Cirque, City Hall, Fig & Olive, Tribeca Grill, Town and Mia Dona. The full list will be on the Restaurant Week website after midnight Friday.
