If I could I would give Yasu a 4.5/5. Hands down one of my favourite sushi places in town. I've had omakase style sushi at both Kaji and Zen and found Yasu to be more traditional in their presentation and choice of sushi (very similar to Zen). Their selection was amazing and I liked the order that they delivered their sushi in. It starts off with a piece that has a light and clear flavour to it, then they give you something with stronger, then light again, etc. all the way until dessert (a ginger ice-cream with candied ginger pieces in it). Just based off of the food, the experience would have been 5/5.
The only minor (and I really do mean minor) flaw was that the wait staff took a bit longer to attend to us than expected. They were very quick to give me water when I initially sat down and explained the menu well but it took them a while to come back when we wanted to order our drinks. I also asked the chef if he could put slightly less wasabi in my sushi and I noticed that he would kind of forget to do that sometimes. But he was super friendly and even joked around with me afterwards when we were ordering extra pieces.
Would 100% come back again. It is expensive ($80 for 18 pieces) but definitely worth it for special occasions.
