Been there twice. Both times asking for gluten free. We were told that everything is. I got sick both times. I will not be returning.
I have been buying One Bite GF Teriyaki & GF Mogu Mogu sauces at Whole Foods, and then I found out the sauces are locally made and used at Sama Zama (formerly called One Bite) that is a Japanese Tapas & Bar in Westport. Because of the sauces, I had try the restuarant too. Just love it and the restaurant and sauces are a must try! Make sure you ask for GF dish options at the restaurant. You will not get disappointed. The sauces also are sold at the restaurant, too!
