Garni Bakery has the best barbari bread and gata in the GTA.
However, the display cases are often barely half stocked, and what stock they do have is very unpredictable. Which is to say, you may walk in with the intention of buying gata or berok, but find that they don't have any on that day.
The biggest problem I have with Garni bakery is that none of the products have the prices listed anywhere and what I get charged for the same product varies week by week. This seems to me to be bad business practice and as a customer, I do not appreciate being charged a different amount at the whims of the cashier for the same product each time I go. On principle, I tend to avoid the bakery for this reason.
