Great experience! There is nothing quite like it, also a great first date idea because you aren't able to comment on your surroundings so you have to dig deep and end up having some really good conversations away from reality.
Also a very eye opening experience, which I thoroughly enjoyed.
We decided to get a total surprise and TO our surprise the food was some of the best I've had. Our surprise starter turned out to be a salmon (or perhaps tuna) tartar. Delicious. Our main course was a gourmet poutine and they didn't need to explain why it was gourmet. I nearly licked the plate.
I would recommend O'Noir again and again. Great food, great experience!
