I've had their tacos at Puce Pop back in March and although have only tried their vegetarian one, it's super flavour-filled and delicious!
If you're going for "authentic" tacos, these are definitely fusion but I don't think you could/should be unimpressed! I got news the other day that they will be some from their HQ on Sunday (the 19th) at 2pm in St-Henri and if you haven't had one, it's definitely worth trying out! Oh and I think it's cash only!
