Three new businesses will soon open at Burlington Mall, according to mall officials. Zumiez, which sells clothing, footwear, accessories, and gear for skateboarding and snowboarding, is opening this month on the first level of the mall near Sears. Sound Lion, which sells, headphones, earbuds, wireless speakers, and other digital sound/music products, and Red Mango, which sells frozen yogurt, smoothies, and parfaits, will both be opening shops next month on the first level near Legal Sea Foods. The newcomers are joining two others that recently opened at the mall: a Subway restaurant, located in the food court on the second level, and a Vans store, selling skate-boarding shoes and other sports-related footwear, on the first level near Nordstrom. Other additions to the mall during the past year include Corn and Co., iFix & Repair, Crumbs Bake Shop, and Bobby’s Burger Palace. Several other stores have moved within the mall, including Justice & Brothers and Spencer’s Gifts.
