Chicago — McDonald’s says that U.S. same-store sales have sequentially improved from late March through May. For the month of May, the Chicago-based fast food giant reported a decline in U.S. same-store sales of 5.1 percent, compared with 19.2 percent for the month of April. Globally, sales fell 29.8 percent quarter-to-date through May. McDonald’s says that 95 percent of its restaurants globally are now open. In the United States, more than 1,000 restaurant dining rooms have reopened with reduced seating capacity. “Our unique advantages, including a high percentage of drive-thru restaurants and investments in delivery and digital, have enabled us to adapt to the changing landscape presented by the COVID-19 outbreak,” says Chris Kempczinski, president and CEO.
