Rather than touting a veggie-friendly menu by highlighting the recently introduced garden burger, it dismissed the vegetarian and vegan lifestyle.
"We even have a garden burger," the spokeswoman said, "in case your teenage daughter is going through a phase."
While many people expressed their dismay on the burger chain's Facebook page, calling the ad "insensitive" and "spit on the faces of every vegetarian."
But the backlash from vegetarians seems to have caused its own backlash, with plenty of people chiming in to offer their support of the restaurant, cheer the ad, and tell those offended to "lighten up."
Regardless, the ad won't be on air for long. Kevin Caulfield, a spokesman for Red Robin, said the ad was always intended to have an expiration date.
"We created a number of ads and we have a rotation schedule that is intended to keep the campaign fresh," Caulfield said. "This particular ad is planned to be out of rotation and no longer on the air very soon."
