We were regulars at Zen back when they were in Scarborough, their sushi quality is the only one that's comparable to Kaji in town.
Aside from the great quality sushi/sashimi, they also make AMAZING tonkatsu, which unfortunately is off the new menu since they moved to Markham, I was so sad!
Since they moved, the price point just gone off the roof, Kaji definitely is a better choice to go now. We still come here for take out once a month, but for dine in... Kaji is much better value.
Their mandarin pie is heavenly, I am not a pie fan - but the only pie I eat is from here.
