After opening Riggio's Restaurant with her husband, Pasquale, Adreana Riggio became well known to the residents of Chicago's North Center neighborhood, who called her Mama. The year was 1952, and the scent of pizza was still unfamiliar in the city. Though the restaurant has since moved to Niles, customers are still treated like family. Diners can dig into savory Italian classics such as veal parmigiana and American dishes such as chopped steak with housemade mushroom gravy. The pizza menu brims with three sizes of thin-crust pies, which can be customized with ingredients such as pepperoni, spinach, or pineapple.
