Shake Shack offer free Avocado Bacon Burger for three weeks

Shake Shack is shaking up the start of spring with a juicy deal for burger lovers. The chain’s burgers are made with a custom 100% Angus beef blend, never frozen, no hormones or antibiotics ever, humanely raised and grazed in the U.S.

And one of its more popular signature burgers, the Avocado Bacon Burger, is a quarter-pound patty with American cheese, topped with sliced avocado, applewood-smoked bacon and ShackSauce — all on a toasted potato bun.
