It's perhaps no surprise that the capital of the U.S. is among the world's most global cities. But some of the characteristics that help put it there might not be so intuitive. Sure, Washington ranks first in the number of think tanks nestled along the Potomac River. It also takes top marks as the seat of international organizations and third for the number of international political conferences held there. But the District of Columbia also is home to a thriving diversity of international cuisine, where it places 10th. Additionally, residents and visitors enjoy a multitude of performing arts venues as well as world-class museums.
