Stock in Chipotle Mexican Grill (NYSE:CMG) (NYSE:CMG-B) has a red-hot following that keeps on growing, and it's already drawing comparisons to Starbucks (NASDAQ:SBUX). But with a $4 billion market cap, and a P/E that's more than double that of McDonald's (NYSE:MCD) or Panera (NASDAQ:PNRA), Chipotle is also drawing questions about its valuation. Is there another Chipotle out there -- a restaurant company that may have promising prospects without the valuation concerns? In this installment of "Fool Video," I ask Fool analyst Tim Hanson whether an up-and-comer named Rubio's (NASDAQ:RUBO) could be the next Chipotle.
