Is this what a McDonald’s double cheeseburger was meant to taste like?

That thought invariably comes to mind when you bite into one of Shawn Nee’s double-cheese smash burgers. The only thing Nee says he knows how to make, the burgers have prompted two-hour-long lines at his Hollywood backyard pop-up, Burgers Never Say Die. They’ve become so popular that this fall, Nee will open his first bricks-and-mortar on Glendale Boulevard in Silver Lake in Los Angeles.
