Ayr Muir, founder and CEO of Clover Food Lab, has grown his restaurant chain from a single food truck to 11 thriving stores but he has no interest in running a regional chain. His ambition is to change the way America eats and his goal is national expansion. As he surveys the competitive landscape and the forces shaping the restaurant industry in 2016, however, he must decide whether to pause the company's planned expansion beyond the greater Boston area and pursue other opportunities for growth or continue to expand Clover's geographic footprint.
