Yeah, pretty much the whole story in the headline there. It's happening on something called "National Taco Day," aka Tuesday, Oct. 4.
The Denver-based chain's chorizo is made of pork and chicken, the company announced. Chorizo is a spicy sausage that is usually made of just pork.
The use of chicken could be a simple menu choice, but it also may point to the fact that the chain has had a hard time sourcing pork that meets its ethical standards. (Remember the carnitas thing?)
Also, at least one stock analyst thinks 2017 will be good for Chipotle, because it just can't get much worse. Basically, revenues are expected to increase from 2016, but they may not recover to 2015 levels, according to BNL Finance.
