This is a late review. I went to Yasu in September 2015. I would give this place a 4 when compared to sushi restaurants in other cities, but given that we are in Toronto, it's definitely a 5. It's a small and cosy place with friendly staff. The fish was fresh and of high quality. The omakase included 16 pieces of various sushi, 1 maki and 1 handroll. Try to get a seat at the bar; watching the chefs do their thing was pretty fun.
