Taking in Big Humphrey's King of the Hill ambience, customers might wonder about the food. But all they need to do is sit down and order. Jasper Vitale uses recipes left by his grandmother, who was born and raised in Sicily. They supplement Grandma's Italian dishes with good ol' American favorites, as if to concede that truckers do not live by the meatball alone. Those who want wine with their pasta will have to bring it themselves.
