Three different experiences, all good. You can check the menus on a number of web sites.
Boma is a all you care to eat buffet with a large selection of foods, some rather standard in preparation and some with African influences. I think it’s one of the best buffets on property if you’re okay with that style restaurant.
Sanaa is a middle tier table service restaurant with a different but still interesting menu. Very good value for the money.
Jiko is one of Disney’s signature restaurants, so top tier pricing applies. Again, some subtle African flavors in some of the dishes, and a number of outstanding selections. Also has a large South African wine selection. We think it’s one of the best signatures on property.
