16 — that’s how many states will host a Shake Shack when the burger joint opens in Detroit in 2017. No date has been set but the location has been selected: 660 Woodward Avenue in the First National Building, adjacent to Campus Martius Park. As with all Shake Shacks, this one will feature local craft beer as well as concrete flavors specially designed to incorporate local products. Shake Shack can currently be found in 14 states and the District of Columbia (and many other countries). Minnesota will be their 15th state this summer.
