Shake Shack is offering a buy-one-get-one-free deal on its Korean Style fast-food menu at participating locations through April 22, 2026.
The offer applies to qualifying orders of two K-Shack items, with the lower-priced item free. It sounds like a great deal, but be warned: there are a few caveats.
For example, Brand Eating reported that the promotion will not be available at airports, stadiums, arenas, travel plazas, and museums.
The lineup

Shake Shack’s Korean-style lineup is built around the same six items fans have been seeing throughout the year.
Amazingly, this isn’t one of those thin promotions where you only have a couple of free items to pick from on a BOGO menu. It’s pretty loaded, and the options are listed below:
- K-Shack BBQ Burger
- K-Shack Fried Chicken Sandwich
- K-Shack Fried Chicken Bites
- K-Shack Spicy BBQ Fries
- K-Shack Spicy BBQ Cheese Fries
- K-Shack Spicy Caramel Shake.

How to order and get the deal
Information from Shake Shack shows the BOGO can be redeemed when you order at an in-Shack kiosk, through the Shake Shack app, or on the company website.
You need to add two qualifying K-Shack items to your order and use the code SPICYSWEET at checkout, in all caps.
Two more exemptions to consider with this offer are:
- The code does not work for drive-thru orders
- The code does not work via third-party delivery apps
Regardless of the constraints on where and how you order, a BOGO deal is still worth checking out.
