It's not the best but it's pretty decent, trouble is as much as I like the seaweed based rolls the pieces with proper fish pieces on top of it are rarer you only get a few pieces compared to the rolls. Whether that's a good or bad thing depends on which kind of Sushi you prefer, better off getting the large packet for greater variety. Like I said though it comes with wasabi and fish sauce which gave it a good added flavour, tasted alright to me. It seems to sell pretty well too, went for some more the other day and it was all sold out, so they must be doing something right.
I'd say it's worth trying, if you want quick and accessible supermarket sushi, it's definitely better than crabsticks quality-wise.
