Tuesday is one of the cheesiest days of the year.
Sept. 18 is the made-up holiday of National Cheeseburger Day, and restaurants are celebrating with discounts and free burgers.
According to a survey by Offers.com, 25 percent of consumers chose Five Guys as their favorite cheeseburger, 21 percent of consumers chose Wendy’s and 20 percent McDonald’s. In-n-Out came in fourth with 15 percent.
But what kind of cheese is the best to top a burger?
The results often depend on the survey, but Livingston, New Jersey-based boutique burger chain Zinburger Wine & Burger Bar has found, based on sales, that American, cheddar and Swiss are the favorite choices.
