I am afraid z-teca doesn't pass muster on at least three fronts--1. Flavor--nothing seems spicy, not even the hot sauce (sic), 2. Taste--I can't wait to finish the meals versus yearning for more at Chipotle, 3. Price--I could eat in at most Mexican restaurants for lesser.
Interestingly, the lines are long-- it must be the winter and the paucity of Mexican options nearby. To their credit, the lines move quickly. The burrito bowls, tacos, quesadillas and everything else is a step down from Chipotle. I have not tried the chips, but I suspect it's not going to be an outlier.
I will be back at z-teca when I am eating in the Path at Commerce Court. Sometimes you have to value diversity over quality.
