Since 1946, White Manna Hamburgers, a local institution in Hackensack, New Jersey, has popularized itself for their one-of-a-kind burger sliders. Using fresh and extra lean ground beef, cooked with onions and cheese, and served on a Martin's Potato Roll, White Manna's sliders have been crowned as the second-best burgers in the nation, according to a list published by The Daily Meal. “Nobody really makes burgers as we do. If you compare us to fast food, it’s totally different. Even if you compare us to gourmet hamburgers, they can’t compete with us,” said Ronny Cohen, owner of White Manna Hamburgers.
