Long known primarily for its shopping malls and office towers, Tysons has undergone big changes in recent years, spurred by the opening of new Silver Line Metro stations. A number of mixed-use developments have opened or are under construction, bringing a slew of new residences along with more restaurants and retail. (Some businesses in Tysons—technically a “census-designated place”—use McLean or Vienna as their address.) Meanwhile, the nearby incorporated Town of Vienna has its own new reasons to visit.
