I am very sensitive to cross-contamination, so I spoke to the staff about their gluten-free handling procedures. They said if you order from the GF menu (last page in the menu), they automatically sanitize the entire workspace before making any dishes in the order you might eat (aka, anything not containing gluten in the recipe). I am (so far, diagnosis only 6 months ago) quite sensitive to cross-contamination, and have not gotten sick there either time I've been since going GF. Also, while they have fantastic GF sushi and sashimi options, their cooked GF selection is very limited.
