'Ohana does offer something for children. However, I'm not sure what they are.
We were asked a few times if our children would prefer something from the children's menu and before I can say anything, my children would say "no thank you" in unison. At one time, our CM "Cousin" was a little startled and laughed. He looked at my children and said, " I see that my cousins love our food!" And to that my children smiled and nodded.
You may want to try and see if they'll eat anything. They have salad, veggies (which my children love), chicken wings, noodles, pineapple bread and all the skewered of course (pork, steak, turkey and shrimp). I find that there are a lot of choices. My children love all of them. I do find that I am spending a long time peeling all the shrimp for them, but it's really good and it's worth it. My daughter prefers the shrimp over the meats. She also prefers the veggies over the salad. But other than that, she eats most of everything. My son, on the other hand, doesn't seem to have any preference there, he eats EVERYTHING.
