Authentic Japanese food and atmosphere, tatami room and sushi bar. Very large menu but nothing noticeably gluten free-when asked, the waitress was considerate and accommodating. Ordered sushi, very fresh. Was served with gluten free soy sauce. I had no celiac reaction from Ginza and enjoyed my time there.
I told the waitress I need gluten free sushi. The chef used a separate space to prepare the rolls, replaced imitation crab with real crab AND used different rice, as regular sushi rice has gluten (i had no idea!) They also left the pickled ginger off the plate and offer Tamari. I was so happy to eat great sushi with no worries.
