Mix-and-Match "Buy-One-Get-One-Free" Deal on Shake Shack's Korean-Style Menu Items Through March 16, 2026

Shake Shack is offering a limited-time, mix-and-match deal through Monday, March 16, 2026, where if you buy any item from its Korean-Style Menu, you can get a second one free when ordering digitally.

The promotion is good on all Korean-Style menu items, including:

• K-Shack Fried Chicken Sandwich
• K-Shack BBQ Burger
• K-Shack Spicy BBQ Fries
• K-Shack Fried Chicken Bites
• K-Shack Spicy Caramel Shake

To redeem the deal, you need to add any two Korean-Style menu items to an order placed via the Shake Shack website or mobile app, or an in-restaurant kiosk using the code "SPICYSWEET". As is typical of such deals, the cheaper item is free.

The BOGO can be used in conjunction with Shake Shack's digital-exclusive $1 sodas, $3 crinkle-cut fries, and $5 classic shakes deals.
