In the following video, Motley Fool consumer goods analyst Blake Bos takes a look at Chipotle's (CMG 0.31%) earnings report. The company showed excellent same-store sales growth at 7.1% and increased its restaurant count by 15% in 2012. Blake tells investors what to watch with the company's first step toward going international, its new restaurants in Canada, and its margins as food costs rise. Finally, he tells us that buying now means paying a premium for a great company, and gives us the metrics to watch to see if Chipotle will hit enough growth to make that premium worthwhile.
