Spur steak is rubbish,usually very dry and the thick layer of sauce over it has to save it by masking how nasty it is.

I once ordered ribs at spur and I will never try that ever again,came as thick under cooked blobs of fat without colour or flavour and almost impossible to bite.
If you want a good steak go to Jimmy's Killer Prawns in Fordsburg,I know it sounds counter intuitive to go to a prawn speciality restaurant to eat steak but honestly they are much better at making steak then they are at making prawns,and I haven't found anywhere yet that makes a more tender and juicy medium to well done rump steak.Their ribs are also quite nice,portion size is a bit dainty on the ribs but the quality is excellent which makes it worth it.
