In a promotion for the new McDonald's self-order kiosks, Gallagher walks in on Galchenyuk customizing a burger and says he can make a better version, leading to the two squaring off in an intense battle on the video boards and trading jabs.
The result is two signature burgers that customers can order using the kiosks. The Galchenyuk is an Angus beef patty with garlic aioli, Swiss cheese, bacon pieces and pickles on an artisan-style bakery roll. The Gallagher is Angus beef with sriracha sauce, cheddar, caramelized onions and bacon strips on a black and white sesame seed brioche-style bun.
This isn't Gallagher's first signature burger at McDonald's. He also had the "Gallagher Trio" in 2014, which contained three beef patties.
