I've heard lots of great things about Schwartz and so my friends and I decided to try it out as we planned our road trip to Montreal. Luckily there was no line when we went, but I heard there's usually a huge line.
To start off, Schwartz is quite small and has that old diner feel to it. Even though it's small, their sandwiches are definitely not small! My friends and I ordered the Montreal Smoked Meat Sandwich, poutine, and the black cherry drink. The poutine was alright, just tasted like normal poutine, but the Montreal Smoked Meat Sandwich was absolutely amazing! There was so much meat stacked in the sandwich and mustard on the bread complimented the meat nicely.
Also, beside Schwartz, they had a "take out" Schwartz store that let you buy the meat to make your own sandwiches at home! My friends and I bought some of the packed meat to take home. The coolest part of this was that there was a tac board filled with napkins pinned on it with people writing comments about where they're from and what they thought of Schwartz!
If you're ever in Montreal, definitely stop by here, even if there's a line! It's definitely worth experiencing it! This was definitely the best part of the trip!
