Fast-casual dining leader Chipotle Mexican Grill (CMG) is committed to fast expansion, undeterred by its carnitas shortage. The company, which had 1,878 restaurants at the end of Q2, opened 97 in the first six months of 2015. It plans new openings “at or above the high end” of its targeted range of 190 to 205 for the full year, Chipotle said in a quarterly filing.
