There are gluten free options. All the nigiri is GF , and then a couple of the special nigiri. Spicy tuna roll is GF. Several appetizers are GF. I got the yellowtail Serrano. Robata has cross contamination and I have a high intolerance so did not even try it. They also have a coconut curry you can eat with white rice. Flavors are not the *best*. I’ve had better sushi but worth trying. The ambience is beautiful.
O-Ku recently added a gluten-free menu. Not only is their food amazing, but as a Celiac person I did not get glutened! They had gluten free soy sauce. They cleaned the kitchen areas and tools special for my food. On the gluten free menu they also have a robata grill that includes some gluten “free” items that the menu mentions are at risk of cross contamination, so Celiac people should avoid those.
