The actual coffee is worth 4 stars but the employees push this place over the edge to give it that one extra star.
The coffee here is definitely enjoyable. Take it from a self professed coffee snob, it's good.
I've been popping in regularly for the past 7 years on my occasional trips to Montreal and it still is my favorite coffee spot in the area.
As with any other place, it depends on how good your barista is. And John Bigsby is one of the best. But I'm sure he'll move on to bigger and better things soon. But this place will almost remain rock solid.
