Magnolia-based Flying Burger is expanding the restaurant chain with a concept new to the company, "Flying Burger Express." The company, with officials from Ouachita Partnership for Economic Development and the Camden Area Chamber of Commerce, will break ground at 10:30 a.m. Tuesday at the site. The location is next to the Sleep Inn Mainstay Suites Hotel, 234 Highway 274 in East Camden. Flying Burger Express is a spin-off of the Flying Burger. The restaurant is described as a "fast casual" dine-in establishment with indoor and outdoor seating as well as a drive through.
