Rib fillet steaks are best when cooked fast at a high temp on a grill or flat pan. Making sure the steaks are at room temperature before cooking will help with making this steak reach its peak potential.
Rib Fillet are great when cooked medium-rare, but also very forgiving when cooked at any doneness, one of the reasons this is such a sought after steak. The thin seam of intramuscular fat that runs through the rib fillet renders beautifully to create a tenderness sensation other cuts can't match.
Rib Fillet usually does not have any off cuts but in the rare occasion it does they will be sent to you when asked to do so.
