There are some things you go do once. When you go to San Francisco you go see the Golden Gate Bridge, when you're in NYC you get a falafel sandwich, and when you're in Montreal, you try a sandwich at Schwartz's. It's a $10ish sandwich of goodness, often likened to the epic NYC equivalent at Katz deli. It's delicious, it is fast, they serve it to you quick with a can of coke if you like and expect you to get moving. This isn't a place you linger for long. Get your photo, devour (and SHARE) your meal and then get out and enjoy the vintage shops up and down the street.
