It's pretty easy.
There is Jiko which is a sit down, nice but not too fancy, restaurant. The menu can seem a bit "different" to some but I believe even the pickier eaters can find something there. They have great flat breads, steak and chicken. I have heard their macaroni and cheese is a terrific side dish but I haven't tried it. Jiko is probably our favorite restaurant on property. The huge South African wine list helps!
Then there is Boma which is a great buffet meal. There are all kinds of African dishes to try as well as plenty of American options. We really like Boma, but we are pretty adventurous when it comes to eating.
The counter service at AKL is Mara. I only ate here once while at the pool. They have a bit more than your standard cheeseburger and nuggets. They have African Stew, flat bread, chicken, and that macaroni and cheese.
The new restaurant is Sanaa. It is in the new Kidani Village building which is the addition to AKV. It is a bit of a walk (10 min.) or a short bus ride from the original building. We haven't been to Sanaa yet but from the reviews, it is on our to-do list. You can see the animals on the savannah right from the restaurant. I recommend you checkout the menu on allears.net.
There are so many good choices for food at AKL, but it really depends on the eating preferences of your group. For my family, AKL food can't be beat. But I wouldn't want to choose for anyone else. Check out the menus for all the restaurants. And have fun!
