Yasu was one of the best culinary experiences of my life.
It's a tiny sushi bar place on Harbord Street, in a converted house. I missed it a few times while driving by. It sits around 10 people around the sushi bar with 2 additional people at a small table. I would highly recommend showing up on time to get a sushi bar spot as seeing the sushi made in front of you is a big part of the experience.
They do only two sittings a night, omakase style, meaning a chef's choice for $80 per person, coordinated by 2 chefs.
Before I walked in, I thought I knew good sushi, but I was absolutely blown away by Yasu. The quality of the fresh fish shines through and the sushi rice was the best I've ever had.
I don't even have pictures of the food because for two straight hours I just sat down and ate. I'll definitely be returning and would highly recommend for anyone in Toronto.
