I think Miracle 558 on Parramatta Road was mentioned earlier. Their website doesn't have any pics, but interestingly their listing on E+B does. The photos on there look pretty real, and it says who works on each day.
I still haven't been myself, but thought this info might be useful for the original poster. I think this place has rear entrance too if busy parra road entrance is a concern.
Cheers
