I went in one day (about two months ago) and asked them to confirm if their sushi rice was gluten free since some recipes use a vinegar with wheat. The host came back and told me the sushi rice was NOT gluten free and that it was not safe to eat anything there with a gluten intolerance due to shared surfaces.
It is possible I encountered a difficult and unhelpful employee, but someone should try to re-confirm this with the restaurant...
No
