Chipotle just has a better spice on their chicken than Burrito Boyz. It's just that simple for me. Also, the chicken chunks are too big in the Burritos. I don't want to come out with a huge piece of chicken every few bites.
Pluses are that Burrito Boyz is a good value.
For some reason calling ahead to order means a slower experience in store. Figure that one out.
