I've not had it at Starring Rolls, but I imagine it must be the same packaged stuff they have at Sunshine Seasons.

We have a supermarket here (HEB) that actually makes pretty decent sushi, so I can't really say 'supermarket' like the PP, but yeah - I definitely wouldn't make the effort to stop in for it.
The cupcakes at Starring Rolls, however...
