What was the name of this Los Angeles area Italian restaurant?

There was an Italian restaurant in Los Angeles in which the diners, friends and strangers alike, sat around one large table while the owner -- a short, stocky man with a thick head of salt and pepper hair -- stood at the head of the table and sang selections from several operas, such as The Toreador Song from Carmen. Sometime in 1987 or 1988, the owner was killed. I believe that police found the owner in a bathrobe on his front lawn, shot in the head (ack!). Anyway, what was the name of that restaurant?
