Just stayed at AKL, breakfast should be easy as a lot of it was standard breakfast choices at both Boma and the QS, Mara.
Lunch and dinner might be a different story, as I don't think you will have a lot of options. QS lunch and dinner at Mara had some standards (burgers, pizza, etc.) and also some more adventurous options (Mara Chicken and Potjie). Boma dinner buffet has a mixture of both non-adventurous food and adventurous food, but it is a buffet so I am not sure if you want to pay the hefty price tag if more than half the options are not appealing to you.
Over in Kidani village, there is Jiko and Sanaa, which both offer steak. I have not eaten at either personally, but both seem to have a lot of spice on their menus. I'd defer to others who have eaten there first though!
