The most common search that sends people to my blog is "Ancho and Coffee Rubbed Filet Mignon with Ancho Mushroom Sauce". It comes up at least weekly (which is pretty common for my low traffic blog).
Have you seen the recipe? It's the first Bobby Flay recipe I ever made, and it is delicious. A special occasion dish. Spicy. Flavorful. The method of cooking the steaks is perfect and superior over the grill, and there are components of the recipe that you can make ahead.
