So for all y'all who hear Cali burrito and immediately expect greatness, you should realize that this joint is not necessarily trying to deceive you!
At least 5/10 times, your Cali Burrito experience (at least in the Bay Area) will not be much more inspired than what you will get on College St.; Re-fried beans look as they do here (in fact at times they will look like this in even some of the famous places such as el farolito http://www.yelp.ca/biz/el-farolito-san-francisco-2 ). Guacamole can also be found in squeeze bottles, but this will be a less frequent violation in a place of decent repute, and regardless of the vehicle of delivery, the guacamole will likely not be as runny as the one served here.
In terms of the taste, my burrito somehow tasted more like a wrap at pita pit than a burrito but I've had much worse food around College/University! The portion was decent, and the major issue I had was holding the damn thing together (the watery sauces didn't make things very easy).
Overall I would say Cali Burrito measures almost 3* for serving food that is relatively fresh and healthy with little wait time right across from University of Toronto. The options in the immediate vicinity of the university have seldom been known for those qualities, and in fact Cali Burrito is a very tiny step up from the shawarma shop it has recently replaced.
