Yasu is very reminiscent of JaBistro, but has better atompshere while JaBistro provides a wider selection. As the kind of person who always orders uni at sushi bars, I can say that the seafood vatiety is nothing special, but the quality might be the best and freshest you can get in Ontario and Quebec. Dinner is a set cost with an option to upgrade the first sashimi course. Doing so gets you a few extra pieces of rarer sashimi. A bit pricey but a good choice. During the meal you sit at the sushi bar and watch the chef prepare your food. You can talk to the chef or just chat with your friends. Overall a pleasant experience, and well worth the cost of admission.
