Covino’s has been serving its Plano neighbors since 1990, and on the weekends, the place is jammed with families waiting patiently for solid pizza, calzones, and hearty pasta dishes served by sweet-natured high schoolers. The Abruzzi bread—perfect flour-dusted pizza dough stuffed with sausage, pepperoni, provolone, and fresh spinach and then sliced—is worth that weekend wait.
