The word "average" has negative connotations but in the case of Katz's, it's not a bad thing. Not all places are exceptional and not all places are horrible. Katz's is in the middle.
The restaurant is located on Dufferin street near Yorkdale. They have ample of parking spaces which is rare in this area. A Burger Priest and a Pizza Nova are besides them in an adjacent plaza.
It was our first time and I liked the Cafeteria style service and decor. You can select a salad or cake on display then go about ordering your choice of sandwich with either fries or soup. We went with a Smoked Meats Montreal Style on an Onion Bun while my wife chose the Rye bread. The meats were good, not the best but not the worst. We also chose the side of different salads along with a piece of cake. My suggestion will be to forego the sides. They are not good. The cake was stale as it was probably on the counter for a long time.
I think I would have loved this place if the prices were a bit more affordable. It was expensive for what we got. I think if you just come for the sandwiches, the prices are more reasonable and you get a better value. Don't order any sides.
Something to think about if you visit this place.
