I used to really like Ho Su. The one on queen west has always been good for me. But this one on Yonge street has been very disappointing. We ordered the yellowtail and green onion ( Niri Hagamachi I think) - it did not taste good at all. I've eaten this roll dozens of times before - here and at other restaurants. We told the waitress that the tuna roll did not taste "right" and she said "it's not Tuna, it's yellowtail." We informed her yellowtail was a type of tuna. She said ohhhh and walked away. No offer to fix the problem, and no apology. Everything else was ok. The kimchi soup was awesome as usual. This location needs to really improve for me to return.
