Chipotle included the drive-thru lanes at 100 of the some 160 restaurants it opened last year. It ended 2020 with Chipotlanes at 170 of its more than 2,750 locations. The Chipotlanes boost "customer access and convenience while also helping increase new restaurant sales, margins, and returns," Chipotle said last month in announcing financial results for 2020. The firm noted digital sales grew by almost 175 percent last year and accounted for 46.2 percent of all sales. Chipotle posted annual sales of $6 billion, up by 7.1 percent from 2019. It said net income climbed more than 5 percent to $355.8 million. The chain expects to open about 200 restaurants this year. Each location typically employs about 25 workers, the company says.
