It has been awhile since I have eaten at Ohana, but if I remember correctly it was the typical child's menu: hamburger/pizza/chicken nugget type of menu
I know for a fact that you can order a hot dog cuz my DS always does. In the past, my DD ordered chicken strips. Now she eats off the adult menu. Both come with french fries.
We ate there 08/07, 10/07, & 11/07. For the November visit my 11 yr. old nephew was with us who eats a very limited menu. They served him a great cheeseburger w/ff. However, we were charged the full adult price (around $26-$28). I think his choices were hot dog, cheeseburger or chicken tenders.
