Popeyes chicken sandwich, which caused social media frenzy, returns

(WXYZ) — It's back. The Popeyes chicken sandwich that went viral during a social media showdown between fast-food chains over the best chicken sandwich, has returned after a brief hiatus.

In August, Popeyes sold out of its new chicken sandwich due to an overwhelming demand. The chain even gave customers the option to "BYOB" – bring their own bun – for a chance to try the popular sandwich.

But now it's back, and on National Sandwich Day of all days.

The company made sure to announce the return of its chicken sandwich on all social media platforms Sunday.
