The best piece of meat I've ever eaten was a double bone in USDA Prime piece of filet mignon. Nothing on it. Just a heavenly piece of meat. If someone had ruined it with any sort of sauce I didn't ask for I would have flipped my lid.
I would say it doesn't need it. It's a nice complement for that cut.
I never order filet, though. I always get the fattier cuts.
Usually béarnaise is served on the side as well. It never tops a filet.
