Separate gluten-free menu clearly listed which sushi options are or could be made gluten-free. They even had gluten-free pad Thai (made with gluten-free soy sauce so not the same flavor but I didn't mind!) The proprietor was very knowledgeable about gluten issues, e.g. saying they don't put masago in the gluten-free rolls because sometimes it's gluten-free and sometimes it's not. They even had gluten-free soy sauce packets. I can't speak to measures to prevent cross contamination, but it generally felt safe for the items I ordered.
