This is a favorite spot amongst our friend group- we love the all you can eat $20 dinner specials. There is a lot of assortment and the sashimi always tastes fresh. The decor is modern and clean (which is a nice change from some other Japanese restaurants in Toronto) and the staff is quick and efficient. Aji Sai gets really busy between 630-9pm so make a reservation ahead of time if you know you are going.
Try the butterfish sashimi-so good! :)
