When I was there in January they had the bobotie macaroni and cheese as an accompaniment that you could purchase (a side order but it was quite large) details below. If you just want the plain white four cheese mac and cheese that they serve, and have been serving for years, then you will need to specifically request that, because it isn't on the adult menu, so they may think you are talking about the bobotie version if you just ask for a side of mac and cheese.
