Wayback Burgers’ Tampa Bay outposts to celebrate National Cheeseburger Day

Wayback Burgers is getting in on the National Cheeseburger Day festivities. To celebrate the food holiday on Tuesday, Sept. 18, all of the Connecticut-based fast-casual burger franchise’s locations will feature a buy-one-get-one-free deal on its Cheeeesy Burger.

Essentially, the Cheeeesy Burger — a cross between a grilled cheese sandwich and a cheeseburger — nestles two made-to-order beef patties and four slices of melted American cheese on an inverted bun that’s been grilled and buttered.

Customers must download the new Wayback app to receive the Cheeseburger Day offer from 10:30 a.m. to close. After making their first in-app purchase, they’ll also score a classic burger on the house.

Plant City and Lithia house the franchise’s Tampa Bay outposts.
