Shares of Chipotle Mexican Grill (NYSE:CMG) (NYSE:CMG-B) have fallen more than 30% over the last year. And while it's been a rough year on Wall Street for many food establishments -- see Krispy Kreme (NASDAQ:KKD) and Starbucks (NASDAQ:SBUX) -- companies like McDonald's (NYSE:MCD) and Panera (NASDAQ:PNRA) have seen their shares rebound recently. Will Chipotle get its mojo back? Is it time to buy shares? In this installment of "Fool Video," I ask Motley Fool contributor Tim Beyers for his take.
