They have their own GF soy sauce. The waitress was really helpful in making sure if anything had gluten products to either withhold it or tell me so that I can order something else.
Staff very knowledgeable about Celiac. Clean grill, work and sushi stations before any GF meal. Changes gloves. Carries GF soy sauce. Katrina and another waiter on top of it! GF yum yum sauce.
