While commenting on the company's results, Steve Ells, Chipotle's chairman and CEO, mentioned (among other things) the company may consider catering at some point this year. Catering sounds "different," but without knowing the associated costs it's tough to get bullish on the concept. I'm not certain this will have much of an impact in the near term. Investors who are paying for growth today want assurances that margin and comps will begin to move in the right direction again. Unfortunately, management only guided for flat to low-single-digit comps for all of 2013. While Chipotle prides itself on being different, I'm not so certain that it is. Yum's Taco Bell has a similar business model and so does Qdoba Mexican Grill, which is owned by Jack In The Box ( JACK). The latter is struggling to compete and posted just 2.4% growth in comps for the fiscal 2012.
