"Spruce, a Michelin-starred restaurant in San Francisco, is famous for its burger that's rumored to induce labor. This myth has made the burger a popular choice among expectant parents and those who have just given birth. Known for its 8-ounce American wagyu beef patty and previously duck fat fries, the burger is only available on the bar menu. Despite not containing typical labor-inducing ingredients, the burger's reputation has spread through word of mouth and social media, drawing families and parents to the eatery." - Paolo Bicchieri
