The response to the first two Shake Shack locations in D.C. was so positive that they've decided to add a third.   Earlier this week, it was announced that the third location will open inside the International Spy Museum (800 F St. NW) next year. Edwin Bragg, a spokesperson for the chain, says that the new location will be on the corner storefront of the museum, a space currently used by the Spy Café.

People love the Dupont and Nationals Park locations, so there's no reason for the newest addition to be anything different.
