Flanked by way of super-sized versions of its signature of a gold color arches, the new flagship McDonald's restaurant in downtown Chicago bears a striking resemblance to its predecessor of 50 years ago.

Like Ray Kroc's original 1955 franchise restaurant in the Chicago suburb De Plaines, the modern outlet features dual parabolic arches that intersect a spilled wedge-shaped roof. Its point-supported glass curtain wall entrance adapts the canted shape of the original metal-framed pick-up windows. And, like the landmark restaurant, red-and-white-striped tiles wrap the base of the building.
