z-tec is a new-ish burrito chain in Toronto. I've been to the one on King Street 3 times - so can't comment on my experience at the other Toronto locations. Their menu is the what you'd expect - burritos, quesadillas and salads. I really liked their chicken - lots of favour, but heavy on the onions. The "burrito bowl" is great and I'd highly recommend getting it. I found the burritos to be really big and I couldn't finish it - and they only come in one size. The atmosphere is nice and perfect for a lunch. Their service could be improved as there are a lot of people working behind the counter. Overall, I'd recommend it to friends but wouldn't consider it in the top 5 burrito places in Toronto.
