Harold’s Cabin and designer Brittany Brandt have once again transformed the restaurant’s upstairs lounge, The Pickled Beat, into a ”White Christmas“-themed wonderland for the month. Making a comeback this year: the upside-down tree and cozy Cabin Igloo, a semi-private rooftop area that seats eight. Soak up the festive vibes with a mug of eggnog-fermented for six months by bar manager Michael DeNicola—or a Naughty Ginger cocktail before tucking into one of the Cabin’s winter stews. 247 Congress St., Tuesday-Thursday, 4-10 p.m.; Friday-Saturday, 11a.m.-10 p.m. www.haroldscabin.com
