Over near Three Mile Harbor, the Blend, the new restaurant opened by the chef and owner of Michael’s, is serving dinner from 5 to 9 nightly. Nick and Toni’s restaurant in East Hampton has teamed up with the Golden Eagle Studio, a nearby neighbor on North Main Street, to initiate a series of dinners with featured artists who will discuss an art-related topic, give a demonstration, or teach an art class at the studio before joining the group for dinner at the restaurant.
