The grocery stores here prepare the sushi themselves. I thought the sushi cook did the all slicing of the stuff, because they are specialists, but now I’ll have to ask. In any case even the cheapest boxed sushi is over $5. That’s not school cafeteria territory, is it?
The stuff here comes pre-boxed. There is no in store preparation required at all.
I think the cheapest is $4.99, and the seaside combo, my favorite is $8.99, but it’s almost entirely sashimi except for the shrimp which is cooked.
