The quality of the Latte varies from one of the best of Montreal to terrible. It depends on the Barista, unfortunately.
The beans they sell are relatively old at times. Some really taste like they were roasted more than 2 weeks which really ruins the Lattes you make at home. I have tasted a huge difference depending on how soon they sell them after roasting -they don't roast them in-house but get them already roasted 2-3 times a week which even adds more time to ruin the taste-.
The seating is average and I think they have free internet.
I still pass by and grab a Latte if I see certain Baristas making them. If you like making your own espressos, I suggest you get your beans elsewhere.
