Ohhhhhhhh yes Schwartz's is it! A must stop for anyone in Montreal. My mouth is just watering thinking about this place. Overcrowded? Yes. Lengendary? Heck yes. Worth it? No hesitations here. I'd wait in the sub zero temperatures of a Montreal winter any day for a smoked meat sandwich.
Schwartz's defines what a Hebrew Delicatessen is and should be. You will never find any place better.
