I recommend three restaurants: the House of Lords Steak House in the Sahara Casino, Battista's Hole in the Wall, and Bob Taylor's Original Ranch House. Sure, you can go to Binion's or Fremont Street, but even though those places were part of the old, pre-Strip Vegas, they haven't made the effort to retain that old glamour.
