Shake Shack, the burger-and-custard chain founded by Manhattan restaurateur Danny Meyer, plans to raise as much as $80 million in an initial public offering this year. But ever the fan of slow, steady growth, Meyer isn't getting in over his head. To this day, the chain doesn't franchise within the U.S. and its IPO is more than a decade in the making. 

With majority backing from Meyer's Union Square Hospitality Group, he launched the burger stand concept in 2001 as a "community wealth venture" to benefit Madison Square Park. But Shake Shack quickly became the go-to spot for griddled burgers and creamy milkshakes.

Now, with 63 restaurants worldwide--20 in the Middle East alone--plus buzzy mentions on HBO's "The Newsroom" and "The Daily Show" on Comedy Central, the Shack has truly gone global. So is it ready for world burger domination? Take a look at its milestones below and decide for yourself.
