This is the place you go to see your kids have fun--if they are open to participating! Coconut Races, hula-type singing to 'Little Grass Shack', marching around the restaurant.
The food is mediocre. Skewered meat (sausages--awful, pork--overdone, and chicken, I think--ok) is easy to forget. Salad is good, potatoes good, and we never even ate the shrimp (cold) that came because it was in-shell and had not been deveined.
My recommendation? Eat elsewhere, then take the family to Ohana for cocktails for the adults, and the kids can join in the fun! No reservations needed, as the lounge/bar is kind of the waiting area for the restaurant--one big area.
Afterwards, go out on the beach to watch the fireworks. Get there in time to grabe the swings. Then, rise the monorail at night.
