I've had pretty good luck asking restaurants for their recipes, you might want to try that if you haven't already.
I've never seen "Luciano" sauce in any of my Italian cookbooks, nor eaten it anywhere I remember, so I'm guessing it's a specialty of the house. It never hurts to ask for the recipe.
Bing (and no doubt Google) gives a number of sources for recipes, as well as some information on Italian film director Luciano Salce. Whether any of them are worth looking for I can't say.
