Having once lived in Astoria, Queens (NY) which has fantastic Greek food, I'm mostly disappointed when I try out Greek cuisine in other places.
I was VERY happy with my meal here.
My spouse and I had tzatziki, spanokopita (as an appetizer), a plate of warmed grape leaves, and a Greek salad. All of it was DELICIOUS.
The service was good and very quick. The atmosphere is perfect and exceptionally clean.
Prices are very slightly higher than what I am used to, but I found that true of most of Montreal. So it can't really be held against them.
I highly recommend this place. It's a gem.
