My second burrito chain of the week, Z-Teca on my burrito bonanza tour! Z-teca is very similar to other burrito chains; they offer the standard fare - burritos, bowls, salads, quesadillas & tacos.
Only one size for their burritos, when I got mine it was an average size. They only offer two tacos on their menu - a bit of set back considering three is the average at other chains.
My chicken burrito was descent but no major highlights. I liked their salsa options.
Z-teca offers a cheap meal options on the trendy King West theatre strip; check it out if you are in the area.
