This place is typically bustling with customers on weekday afternoons. As far as the AYCE Sushi($11-14) is concerned -yes, generally conveyor belt sushi and AYCE are sub-par when compared to a slow sit down sushi bar. The menu features a lot of variety, yet everything tends to be drowned in rice. Still, you can get some decent Katsu and Grilled Salmon from their list of non-sushi items. Avoid the hand rolls like the plague, since the seaweed is impossible and tastes like plastic.
My beef with the restaurant is the lack of staff during the obvious rush hours. It's a challenge to flag down a waiter for just about anything, and sometimes it will leave you extremely frustrated, so I wouldn't recommend coming here if you're at all pressed for time.
It's definitely nowhere near great sushi in the GTA, but compared to restaurants in the area, like Wasabi, Aji Sai might be worth a visit.
