“It’s time to bust out the Buddy Holly records and dust off the hula hoop,” according to Jack in the Box. The burger chain has rolled out new menu items with a 1950s vibe, including Sourdough Melts and a Chocolate Malted Crunch Shake.

The Sourdough Melts feature the chain’s sourdough bread with either a jumbo beef patty or chicken fillet topped with grilled onions, a slice of American and Swiss-style cheese, mayo-onion sauce, and sweet mustard. The Chocolate Malted Crunch Shake is made with vanilla ice cream, bittersweet chocolate syrup, and chocolate-covered malt pieces.

“We live in a very hectic, technological age,” said Michelle Vespa, Jack’s director of menu marketing and innovation, in a statement. “Foods like patty melts and malts not only remind consumers of simpler times, but they also provide a sense of comfort and a feeling of home.”

The Sourdough Melts are available for a suggested price of $2.99 with a beef patty and $3.49 with a chicken fillet. The Chocolate Malted Crunch Shake is available for a suggested price of $1.99 for a small, $2.29 for a medium, and $3.29 for a large.

The chain is also offering a special Diner Melts Combo that features a Sourdough Melt, Chocolate Malted Crunch Shake, and an order of the chain’s new Natural Cut Fries.
