Eminem surprised guests by serving up pasta at the grand opening of his Mom’s Spaghetti restaurant in downtown Detroit on Wednesday.

Slim Shady himself was not expected to be there but drove up in a car and soon appeared in the serving window.

The name of the rapper’s restaurant is in reference to a line from Eminem’s 2002 hit “Lose Yourself.”

“His palms are sweaty, knees weak, arms are heavy,” Eminem raps in the song. “There’s vomit on his sweater already, mom’s spaghetti.”

The restaurant, located on Woodward Avenue, has limited seating and a walk-up window.
