Hidden from me, at least. Thanks to waylman, I gave it a try again. I ordered a veggie roll combo to go (spicy avocado, asparagus, yam $10 and change) and then went and did some stupidmarket shopping. So I didn't get down to it for prolly an hour. And it was very good, even after languishing in a stryo clamshell all that time.
The yam still had a hint of crispness in the batter, the asparagus was al dente and the spicy sauce on the avocado was enhanced by chopped green onion. The sauce was also more interesting than the usual sriracha. The only thing that suffered was the nori which is completely understandable, and only on the asparagus roll was it noticeable.
I love that the filling to rice ratio is so high ie. the rice is thin, and that they seem to be using good rice. I'm looking forward to dining in and trying some more items. The room is pleasant and the staff very solicitous (I think mostly Japanese). They told me 10 minutes and it was 15 but that is not bad for 7 pm. It's equidistant between home and office, so I may try lunch there soon. Thanks again, waylman!
Here's a pic of the goodies after their perilous journey home.
