I've eaten at a lot of Japanese restaurants, and this might just be my favorite.
My wife and I stopped in on a bit of a whim because sushi is our traditional anniversary meal, and this place is *legit*. Toronto's a super multicultural city, but most Japanese places you go to are run or staffed by other East Asians slinging Americanized fare.
Daio is Japanese owned and run, oozes atmosphere and authenticity, and the food is just *awesome*. The service was also super friendly and attentive, and I could hear our waiter knowledgeably discussing things like what fish were in season with other guests.
I knew I would have a good time based on these other reviews, but I was still absolutely blown away. Can't wait to come back!
