Cook, the award-winning restaurant with locations in both Needham and Newton, Mass., invites everyone to bring 10 or more friends to either of its locations to enjoy free bar space and food. Get out of work early to celebrate friends in true Thanksgiving fashion. If those three hours aren’t enough, all guests are welcome to stay past 6:30 p.m. to order from the a la carte menu and continue the celebration.
