I just got a notification from the Moe's app. "Buy a Bowl, get a free Treat Yourself".
A "Treat yourself" is a 22oz drink and your choice of a side of Guac or Queso. Download the Moe's app and give it a try.
*You must buy a bowl for the free drink and side.
Edit: YMMV, looks like some people aren't getting it. NYC here and it worked.
