Ferrara Candy Company is bringing its new headquarters to the Old Main Post Office in downtown Chicago, officials announced Thursday.

The move from Oakbrook Terrace back to the city where the company first started will bring 400 new jobs, Mayor Rahm Emanuel said.

“We are welcoming a great company with deep roots in Chicago back home,” Emanuel said in a statement. “Chicago not only leads the country in corporate relocations every year for the last five years, but we lead the country in the growth of jobs in the food industry.
