Other companies with relatively new downtown Chicago offices are tacking on urban space to reap some of the same benefits. McDonald's opened a digital office in the River North neighborhood earlier this year to complement its sprawling complex in Oak Brook and its first dedicated digital office in San Francisco. When Walgreens moved hundreds of its workers from its Deerfield headquarters to downtown in 2012, the idea was to attract tech-savvy workers more qualified for its e-commerce jobs, said spokesman Michael Polzin.
