Had Chipotle twice recently. While on the go in Sarasota, FL, I tried the guajillo steak. It was very tasty, much better than the regular steak, but not sure if it's worth the higher cost compared to regular steak (and even higher cost compared to my usual sofritas).
Last night near home, I tried the chicken al pastor. I enjoyed the heat with a hint of sweetness that the regular chicken lacks. If they keep it on the regular menu, it would become my second choice if I don't feel like having sofritas.
That said, whenever given a choice, the kids will choose Qdoba over Chipotle 90% of the time.
