Orange County is not lacking in regional Mexican dives, from Baja California to Oaxaca and all points in between. But only Los Chilangos, a relative to one of the county's first Mexico City-style restaurants, changes its menu weekly to offer all of the dizzying street foods of the famed cuidad: fried quesadillas stuffed with flor de calabaza or truffle-like huitlacoche; massive pambazos, a sort of torta smeared with potato and chorizo and placed on a griddle to burn; or even tlacoyos, primordial crepes filled with fava beans.
