Oh Akki!
I used to come here with my wife nearly weekly when we lived in the area!
Great ambiance, friendly staff. I'm always shocked that the restraunt is relatively low key and low traffic. Their food is always consistent and great.
They now have expanded their menu to sushi, which is good. However, their key seems to be cooked isakaya type dishes. Their hot food is simply delish.
Their udon is always trust worthy and has wonderful garnishes. My fave is their tempura udon. Great apps (tried all of them--cannot fault a single one!). We went so often that they knew me + my wife's order by heart. I recommend this spot highly. Definitely a hidden gem in Vaughan.
