While the line was long, we didn't have to wait very long since the turn lover is quite quick -- people moving in and out of the restaurant.
It is quite squishy inside but we sat at the counter and ordered 2 Montreal Smoked Meat sandwiches which they gave us immediately. We were in and out within 10 minutes -- granted we were so hungry when we sat down so the sandwiches were basically engulfed within minutes.
I have to agree that the sandwiches are good BUT there are definitely other places in Montreal that serve better smoked meat sandwiches. Others may disagree with me but I definitely would not return to Schwartz unless someone else wanted to try it. It's worth the try but if you've visited Montreal multiple times, there are other options out there to avoid the line and price. Each sandwich was around $10 and with two cans of pop our total for 2 people was $30 -- making this the most expensive meal we had in Montreal for the least amount of food.
Overall, I would say it worth the try because it is quite good but it's not a must-go-to place for me.
