A hidden gem! I am so glad my friend recommended me this place.
Venue: It looks average but clean and it has some nice private booths. To be honest, I passed by Daio on Carlton Street many times but really never gave it a second look. $$$
Food: Wow! We had many appetizers and sake. Some of the excellent dishes are Black cod, Agedashi Tofu, very very fresh tuna, salmon and Hamachi sashimi, soft shell crab,... Presentation of food was beautiful and inviting. $$$$$
Service: she was very friendly and pleasant. $$$$
Conclusion: I definitely like how good/fresh the sashimi were. Freshness is what I look for in a sushi place. There are way too many sushi joints in Toronto and some really serve plastic rubber sushi. Daio Japanese Restaurant serves amazing and serious food.
