National Cheeseburger Day is officially TODAY, September 18 and many restaurants are celebrating with deals, BOGO's and freebies!

You'll find offers from Hwy 55, Sonic, BurgerFi, McDonald's and more!

Hwy 55 Burgers, Shakes & Fries

Hwy 55 Burgers, Shakes & Fries is celebrating National Cheeseburger Day by offering their Lil’ Cheeseburgers for only 55 cents on Monday, September 18, 2017! That includes cheese and any of their 13 toppings!

The Lil’ Cheeseburger is normally priced at $3.39 so the National Cheeseburger Day is pretty impressive. They are hoping to set a record for most cheeseburgers sold by Hwy 55 in a single day and at only 55 cents each, I would think that's definitely possible.

From 5 p.m. to close, Hwy 55 will feature the $0.55 fresh, never-frozen hand-pattied burgers topped with its secret seasonings and a choice of American, Swiss, provolone, and pepper jack cheeses.

The offer is for dine-in only and there is a limit of two per guest.
