The sushi rice, most sauces, "krab" and roe all contain gluten. Staff is sometimes on top of it but it is inconsistent. There are not many GF options left. I've ordered in person and for delivery several times over the years. The last few orders were too inconsistent for me to feel confident eating there moving forward.
