The new Portillo's will be at Addison and Kimball, just east of the Addison CTA Blue Line station and the Kennedy Expressway.
The 9,000-sq.-ft. space will have seating for more than 280 guests, a seasonal patio, a parking lot and a double-drive-thru, for guests who'd like their Italian beef and chocolate cake to go.
Portillo's said the decor inside the new restaurant will showcase Chicago in the 1920s and 1930s, taking diners from the Roaring Twenties, to the Great Depression and the New Deal.
