While this restaurant did not have GF soy sauce or any sushi rolls, I was able to share with them my allergy card and safely order sashimi - tuna and salmon. They gave me salt to put on it, thankfully I also had my own GF soy sauce. Fish was excellent and one of the sushi chefs understood my allergy.
