Wow. The spicy pulled pork is one of the best burrito and quesadilla combinations I have ever had. I've been back multiple times since my first visit and haven't been disappointed.
I always end up eating the burrito there so the sauce doesn't go through the burrito by the time I walk home. You can take the quesadilla home with no issues.
This is by far the best burrito in Toronto - hands down - accept no substitutes. Don't be fooled by the fact this place is in a basement. Makes it even better in my opinion.
