It’s no secret that Shake Shack serves one of my favorite burgers. Besides their awesome burgers, Shake Shack also offer amazing custard and solid fries- I highly recommend that you order them with cheese!

Check out some posts that I’ve written about the chain:

• Food Review: The Bacon CheddarShack

Shake Shack has been expanding at a steady pace. There are Shack’s located around the US and also in many international locations. Last summer, Kim, Lucas and I visited locations in the UAE (Dubai & Abu Dhabi) and Bahrain.

On August 16 Shake Shack will be reaching a milestone. The 100th location will be opening at Boston Seaport (77 Seaport Boulevard). Congats to Shack!!!

To celebrate, Shacks around the world will be giving away a free single ShackBurger (or a burger or equal or lesser value) to the first 100 customers before 12PM. (The offer is good at all locations worldwide excluding stadiums and ballparks.)

*All U.S. Shack locations will be opening at 10:30AM.

Will this special offer encourage you to head out early to a Shack for a free burger?

I’ll probably pass since I’m not planning to be by a Shack tomorrow morning but then again you never know!
