Doubtless the best Omakase sushi in Toronto.
The only downside (however pretty obvious) is that most of the fish is actually from Mexico/Europe, some had a very fishy taste.
In terms of authenticity I think this is a 'fusion' Omakase because of the different fish used from traditional Japanese sushi due to unavailability in North America.
Every piece comes with Wasabi and Soy sauce so there isn't much variation in tasting - although I would assume the only reason every piece is covered in savoury soy sauce taste is to overcome the REALLY fishy taste from the Mexican / Portuguese fish.
I gave 5 stars because of the service and good Sake pairing. You actually need to chug some sake to get rid of the fishy aftertaste on your taste bud.
This is a good entry-level Omakase outside of Japan , without the steep price either.

Forgot to mention - on the weekend that we went to this place, me and my husband drove over to J-town up in Markham and Taro fish market in North York as well - both place had EXACTLY the same selection of fish from Yasu. I would suspect that they had the same suppliers or Yasu just bought the stuff from either of the 2 places.
Cost us around $50 to purchase the fish we liked from the previous day tasting (definitely NO PORTUGUESE SARDINE EVER) and made a homemade Chirashi Don and had WAY MORE FISH than the Omakase at Yasu.
So for people who can make an easy at-home Japanese Chirashi Don and live closer to those two stores, I would recommend getting the fish and make yourself a tasty treat at home - the fish are just as fresh and no hassle for reservation.
