Sica was the longtime owner of the Sir Sico restaurant in Sun Valley. Beginning in 1959 he fought a lengthy battle to obtain an entertainment permit for that establishment. For seven years it was opposed by the Los Angeles Police Commission on grounds that he had a lengthy record of arrests for gambling and that he was associated with "known criminals" especially his brothers Alfred and Joseph "JS" Sica. He finally won the permit after Los Angeles Superior Court Judge Alfred Gitelson noted that Sica already had a liquor license and that addition of a piano bar had no relation to any allegations of bad character.
