Overall a good restaurant. We requested and got a dedicated (and reasonably large) gluten free menu although many items say “soy” in ingredient description. The waitress indicated that they use tamari for gluten free options, and assured us that grill for gluten free options was separate from grill used for any products with soy sauce.
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.
