I grew up on Schwartz's, unlike many of my fellow Montrealers, I actually really like the place. I personally go on off-hours, around 2 PM, because the line is not as long. Always order it fatty, if not it might be on the dryer side. It is a bit smokey, peppery, fat. I love mustard so there's always an extra mustard on my part, however, it might not be everyone's jam. The pairing of choice is Cotts cherry cola, and the fries and pickles are great too.
