Phoenix, Arizona (CNN) -- It was an ethnic twist on an American classic, the kind of thing that some people consider appealing and others frightening. Pinto beans, diced tomatoes, salsa and jalapenos top a hot dog that's grilled to perfection. It's 10 o'clock on a Saturday night at ground zero in the immigration debate. The hot dog vendor, a woman from the Mexican state of Sinaloa, would normally be doing a brisk business. Her cart is across the street from a popular Latino dance club that used to be frequented by Mexican-Americans but is now normally crammed with Mexican immigrants.
