Being Jewish and having grown up in Thornhill (T-Hill represent! :) yes I just said that) obviously I've eaten here occasionally over the years...and I know that, for deli sandwiches and platters, party sandwiches, chopped liver and the like, this place is better than Pickle Barrel. At peak hours on weekends, people practically line up out the door here. That's because their food is consistent and above-average quality.
So why only 3 stars? I ordered a medium-fat Montreal smoked meat sandwich to-go the other day and was disappointed. The meat was cut way too thick, and the whole sandwich just didn't thrill me.
A tip for deli fans: Katz's on Dufferin is not to be missed.
