The owners of a restaurant in Minnesota claim they’ve been seeing an “influx of pregnant women” ever since news of their alleged “Labor Inducer” burger started making headlines across the state. The owners of The Suburban, in Excelsior, Minnesota, say that between one and three pregnant customers have been stopping in per day since the beginning of last week, when the burger’s purported labor-triggering properties were made public.

Co-owner Ashley Berset told Fox News it all started back in April, when Enrique, the chef at the restaurant, was experimenting with recipes for the then-upcoming Twin Cities Burger Battle, and offered samples of his newest creation to co-owner Kelsey Quarberg, who is also Berset’s sister.

“My sister, Kelsey, was nine days away from her due date with her first child and liked the sample so much that she ordered a full-size one as well,” Berset told Fox News. “About seven hours later she went into labor with her baby Sam.”

Berset said the burger became known as “The Labor Inducer,” and was added to the menu after it took third place at the Burger Battle.
