Shake Shack—the fast-casual restaurant chain thought to have one of the best damn burgers on the market—started as a lowly hot dog cart in New York City's Madison Square Park in the early-Aughts. By 2004, the Danny Meyer-led burger joint had a permanent kiosk in the park, with lines winding down East 23rd Street. And now, some 12 years later, the restaurant chain is all grown up, preparing to open its 100th outpost at the Boston Seaport on Tuesday, August 16.

In honor of the occasion, and as a showing of gratitude to its customers, Shake Shack will be giving away 100 free Shack Burgers at all of its locations worldwide. The giveaway begins at 10:30 a.m. on Tuesday at each restaurant—excluding outposts located in stadiums and ballparks—and will run until noon.

While Shake Shack might not be everyone's idea of a healthy Tuesday morning breakfast, we're guessing the complimentary burgers will go pretty fast. For Shake Shack, however, the company's 100th restaurant is an impressive benchmark, but also just one more step in the greater quest for global burger domination.

“From our first-ever Shack in Madison Square Park twelve years ago, to so many incredible places in between, opening our 100th Shack at Boston Seaport is an epic milestone for us,” Randy Garutti, ​Shake Shack's CEO, said in a press release Thursday. “We’re overwhelmed by the love and enthusiasm from our fans around the world, and this moment wouldn’t be possible without them. Here’s to bringing more Shacks to local communities around the world!”

More Shake Shacks around the world is fine with us, especially if they keep doling out free goods.
