Krystal is running a new promotion where anyone can enjoy all-you-can-eat Krystal Burgers and Fries every day for $5.99 at participating locations.

In order to take advantage of the dine-in only deal, simply stop by any participating Krystal and when you buy four Krystals at regular price, you’ll receive two more at a time until you’ve had your fill, or you burst, whichever comes first.

The offer is valid on Original Krystal Burgers and Fries for a limited time only.

The Original Krystal features a grilled 100 percent beef slider patty topped with diced onions, mustard and a slice of dill pickle, all on the chain’s signature steamed bun.
