We have been at Ristorante Quattro three times during our 5-day stay in Montreal. One other day was Sunday, when they are closed (completely understandable for family reasons but pretty much regrettable for us, poor tourists :-) ), the another day was the very first one when we simply have not known the place yet. I guess this says everything about the level of satisfaction :-)
The Italian food is superb (or marvelous or perfect - pick your choice of the word, each matches), the wines they offer are perhaps even better. My personal favourite dish was the pappardelle and the favourite wine was the one made of negro amaro (an Italian red one from Puglia) but the Ceasar salad, the calamari, the polipo and the pasta with frutti di mare are all in very close competiton, not to mention the soufflé di cioccolato and the créme brulée... (I would also recommend a white French wine we tasted, the name starts with B, unfortunately I have forgotten the rest and could not find their wine list over the Internet while writing my review...) Besides the pastas their veal scaloppini is also quite worth a try.
The service was basically spotless by my measure, the staff is undoubtedly very friendly and helpful.
For those whom this is important: they REALLY are gluten free friendly (i.e. this is not just a marketing stuff), the entire staff is well aware of the principles and they can offer almost all dishes and desserts in gluten free version. So all those who are suffering of this problem could have a very wide choice here.
Nino, the owner, has some really nice personality - a true Italian, very friendly, my impression was he would do everything in his capacity for the satisfaction of his guests.
The restaurant is in Old Montreal, just few steps from the famous Basilique Notre Dame. The lookout and atmosphere of the place was really nice for me, especially for dinners, when they were quite full - the presence and chatting of others was not disturbing at all but resulted in a very happy and nice atmosphere. It gives a just-fine background, however, you can easily focus on your partner and do not need to speak loudly to be understandable.
About the prices - if you are looking for something cheap, forget the place. If you could afford about 200 CADs (incl. taxes) for a complete very tasty three-course meal for two with a bottle of really very nice wine and you are looking for some place that is worth every of your cents, this is definitely a place worth to try.
I guess, after all the above no one could be surprised that I definitely recommend this place.
If you read this, Nino, thank you and the staff very much again for the experience, I will definitely return next time being in Montreal.
