This is a tiny sandwich shop that's related to the legendary steakhouse Barberian's, just a few spots down the street.
The food is really good. On my most recent trip I had the schnitzel sandwich, which was fresher than you would expect due to the cucumber mayo it came with. The schnitzel was crispy and well-fried, although it could have used a little more seasoning. I also ordered the steak fries which were well-done but a little too thick and potatoey for my taste. They also could have used some more salt.
There is almost no seating inside, but they set up chairs outside in the summer.
Be warned that the portions are enormous. On a previous trip I had the Harrison burger, which came with fried cheese on top. It was delicious, but the size was overwhelming going back to the office after lunch, and I'm a big eater. Great value for money though. You could even split a sandwich with a friend for a smaller lunch.
This is a great lunch option for the neighbourhood, you can do much worse so close to the Eaton Centre and Dundas Square.
