I tried the Montreal Smoked Meat Sandwich and was not disappointed. The sandwich tasted fresh and was so thick with meat I had to nibble at the edges. The pickles they garnished the plate with were also delicious.
Although a sandwich and a can of coke came out costing me $9+, I would definitely come back. It's hard to find a great sandwich in this city and this place can definitely provide you with that.
St. Jamestown Delicatessen was full of faces that felt familiar and were very friendly. It has big windows so you can look out into Cabbagetown while you eat. The atmosphere was pleasant.
I can imagine this place being very busy at lunch time. I went around 3:30pm on a Sunday and it still had a steady stream of customers.
