Broadly speaking this facility is for BA customers travelling First to Cape Town.
As mentioned above, it's the same as the CCR, see the Forum Dashboard. The T5 Flounge options remain available since that is what most passengers in the lounge will be eating.
I can see that on the sign, Oneworld F passengers seems can use the facility
