The episode aired on Friday, October 3, 2014, and sure enough on Saturday, October, 4, 2014, it was on the Chili's menu.
The burger features features a 100% USDA Choice beef patty, tangy slaw, hand-battered and fried house-made garlic dill pickles, and Chili's classic BBQ sauce, on a toasted potato bun. It's available through December 14, 2014.
While Chili's is touting the one-day, overnight turnaround, it's more likely they had a bit more notice as the episode was probably taped earlier this year. Still, when the development of some menu items can sometimes take years, a few months turnaround isn't bad at all.
