You picked a bad month to quit eating chocolate. The annual Taste of Chocolate Festival is coming back to Harvard Square for its 12th year in a row from Friday, January 24th to Sunday, January 26th. All weekend long you can come sample chocolaty treats from your favorite Harvard Square businesses, like traditional Italian hot chocolate from Amorino Gelato, the chocolate chip bagel at Black Sheep Bagel Cafe, the red velvet brownie at Parsnip, and much more. The main event is the free chocolate tasting on Saturday in Brattle Plaza from 1:00-2:00pm, where more than a dozen local businesses will be offering complimentary treats to a throng of Boston chocoholics. Get there early, the lines will be long! There’s no admission; click this way to check out the complete lineup.
