Care to spend an entire weekend indulging in chocolate? Of course you do. Head to Harvard Square from Friday, January 25th through Sunday the 27th for their third annual Chocolate Festival. You and your cocoa-loving friends can get in on the fun like free tastings, chocolate cocktails at Grafton Street Pub & Grill, special desserts at Harvest and Henrietta’s Table, and chocolate-laden teas and dinners in the dark at UpStairs on the Square. Check out Harvard Square Business Association’s website for a complete listing of events and times and then call the restaurants directly to score reservations where necessary.
