Although there is a restaurant at K.D. Station named Ruth's Cosina, it's not affiliated with Castillo. In 1993, the family returned to Sioux City. In 1995, Castillo opened Ruth's Original Cosina on Pierce Street. There, she prepares meals served 11 a.m. to 2 p.m. Tuesday through Saturday for lunch and from 5 p.m. to 9 p.m. Tuesday through Thursday and 5 p.m. to 10 p.m. Friday and Saturday. It's more Americanized.
People seem to love it like that.
She hopes her customers will visit before she retires. But whatever Castillo does won't involve moving away from Siouxland.
