"Tierno! Jugoso! Crujiente!" reads the slogan on the outside of the chicken box. And "Tender! Juicy! Crunchy!" is a pretty fair description of the chicken at Pollo Campero, the fast food fried chicken chain that recently invaded Houston from Guatemala. The crust, formed by a simple flour dip, is very crisp. And the meat is marinated before it's cooked, so it stays extremely moist. But the most astonishing thing about Pollo Campero's fried chicken is how little grease clings to it. The fried chicken here is served with tortillas and salsas. The day that this location opened, television news teams were on hand to report that Guatemalans, Salvadorans and other Latin Americans were standing in line for up to five hours to get some Pollo Campero.
