“From our early introduction into plant-based options to bringing the rare indulgence of truffles to our menu with the new Bacon Truffle Angus Burger*, our customers have come to expect innovative and unique menu offerings, and we’re thrilled to be the first quick service restaurant to be testing CBD infused options,” said Patty Trevino, Senior Vice President, Brand Marketing at Carl’s Jr.

The burger will only be available for one day or until supplies last and will cost $4.20.
