First and foremost: Ignore the exterior of this place. It looks like a dump from outside and immediately conjures images of a low-rent, dirty interior that is the opposite of the truth. Inside the place is remarkably pretty, well-lit and thoroughly enjoyable.
The food is traditional northern Indian fare for the most part and done well. The sauces are slightly less complex than the best I've had (thus the lack of one star) but for the Montreal Indian scene, this is near the top of the class. Service isn't what you'd call friendly but it's competent and quick and there is clearly a serious commitment to quality at every step of the food creation process.
We had: Incredibly fresh, fantastic samosas, shahai paneer (medium), butter chicken (death spicy by request), mango lassi and fantastic garlic naan.
Will return.
