For the third year, American’s Test Kitchen—Boston-based recipe gurus that have a hand in both the television and publishing worlds—hosts ATK Boston Eats, a festival highlighting the area’s best chefs, bartenders and eateries that takes place October 24–26 at ATK’s Seaport headquarters. The centerpiece, a tasting featuring more than 30 top restaurants and live chef demonstrations, takes place October 26 from 2–5 p.m., while celebrity chefs like Joanne Chang of Flour and cocktail wizards like The Hawthorne’s Jackson Cannon showcase their skills for hungry and thirsty patrons at one of three separately ticketed evening extravaganzas spread across the event’s duration.
