I heard lots of good things about this place but was disappointed. The tortilla reminded me of the microwave burritos from the supermarket. That just made it fail right there.
I won't even start with the contents. With a name like Mission, I was hoping for more. Taco Bell is twice as good, twice the size and half the price.
Note - this was in November 2008. I don't know if it's changed from then but I don't want to risk it and waste my time and money the next
time in Toronto.
