I've dined in and gotten takeout here with no issue. No GF menu, but the online ordering system has a gluten allergy option for the items that can be adapted - basically, any sushi that isn't fried and doesn't have crab stick or eel. I've tried several rolls (Healthy Ichiban and Double Spicy Tuna w/o tempura flakes are probably my favorites) and haven't gotten sick. They've provided GF soy sauce in the restaurant and packets with my takeout orders.
