Heart Of Jesus Retreat Center

Tucking up her navy suit pants, Isabelle Villasenor kneels to mop up a spilled soda at her Cypress McDonald's. Quickly, she dispatches a clerk to fetch a refill, flashes the frazzled mother an I've-been-there smile and assures her, "We'll getchya another one." Customers pushing strollers toss her hellos. They ask about her daughters, whom they've watched grow up. "So Jenny's getting married!" says a cheery woman slurping a Coke. During the lunch hour, Villasenor, 48, parks her gleaming white Mercedes outside her newest addition, a McDonald's shoehorned inside a Cerritos Walmart.
