Sakura Sushi is one of my cheap and affordable sushi joints in Markham!
I usually order rolls at these restaurants as you can't go wrong with a red dragon roll (8.95$) - dynamite roll topped with salmon . I also ordered a golden dragon roll (8.95$) which is a dynamite roll topped with unagi and salmon.
I'd recommend the golden one as it is the same price and you get both salmon and unagi! The restaurant is snug so it'll likely only fit a group of 6 max. Great for lunch too.
