The childhood days of trick-or-treating are gone, but that doesn’t mean you can’t have sweets on Halloween. And ArtBar is making the good stuff, too — housemade candy bars that’ll be better than any Snickers, Twix or Kit Kats you can buy. Swing by the Edwin Land Boulevard spot between 5:00 and 10:00pm for dinner, and you’ll score a complimentary appetizer along with the confectionary creations. Free food, sugary eats, what’s not to like? Give 617.806.4122 a ring with any questions or book your table online.
