National Cheeseburger Day 2020: Find deals and free food Friday at McDonald's, Applebee's and more

Friday is considered one of the cheesiest and beefiest days of the year.

Sept. 18 is National Cheeseburger Day and restaurants are celebrating the made-up food holiday with discounts and free burgers. And unlike some other food days, this one isn't canceled by the coronavirus pandemic.

McDonald's, which is experiencing shortages of some ingredients because of the popularity of its limited Travis Scott Meal, will still have a Cheeseburger Day deal Friday. For one day, the fast-food giant will offer double cheeseburgers for 50 cents with an offer on its mobile app.

Ahead of National Cheeseburger Day, Wendy's announced the return of pretzel buns and "the new and improved Pretzel Bacon Pub Cheeseburger."
