Occupying the old Zamora-Chavez family home, which was built in 1840, Casa de Fiesta Mexican Grill is every diner's delight. The huge windows of this restaurant offer an exceptional view of the Plaza. Begin with a Nachos de Fajita appetizer or chile con queso. Entrees of tacos, enchiladas and burritos are served with rice, beans and sopaipillas. The house steak, which is a tender 8-oz rib eye, is an inexpensive favorite. Burgers, sandwiches and several rather creative salads round out the menu.
