Boma's is in AKL. It's a buffet and the restaurant itself is pretty noisy.
The food however is plentiful and in great variety. The flavors on a lot of it are a little different then what you are used to, since its an African buffet.
My son loves the variety of sausages they offer and they have excellent prime rib.
And as everyone mentions the desserts are awesome.
They have a full selection of salads, soups, vegatables, and meats to choose from. So if you don't like one thing, don't eat it, just try something else.
There is a kids buffet too, which offers, chicken fingers, mac and cheese, etc. for the little ones, who aren't adventurous.
Ohana's is my family's other favorite. It's in the Polynesian. It's another all you can eat spot, but its served family style. you start off with a banana flavored bread and they bring out a tray with rice, spring rolls, and salad on it. They also bring out sauces, there are three, one is peanut, another is mango, and I can't remember the third. (Guess which two I use.

)
The main meal is grilled meats. Steak, Chicken, Turkey and Shrimp. Which they bring by on large skewers and put on your plate.
In between the eating, they have the kids come out an do various activities. Hola Hoops and coconut races.
Dessert that comes with the meal is Pineapple with a Carmel dipping sauce.
Both restaurants are very good. You can't go wrong with either. Boma's is also good if you want to check out the Animal Kingdom Lodge. It's a beautiful resort.
Have a good trip!!
