This Halloween, Shake Shack UK is bringing treats, not tricks — and they’re seriously tasty.
On Friday 31st October 2025, burger lovers can sink their fangs into a frighteningly good deal: buy one SmokeShack burger and get another completely free at participating Shake Shack UK locations.
Double the SmokeShack, Double the Flavour
Made with 100% Angus beef, applewood-smoked bacon, chopped cherry peppers, and Shake Shack’s signature ShackSauce, the SmokeShack is a fiery fan-favourite. Served on a toasted potato bun, it’s the perfect combo of smoky, spicy, and juicy — and this Halloween, you’ll get two for the price of one.
Whether you’re out trick-or-treating or gearing up for a spooky night in, Shake Shack’s latest offer is hauntingly irresistible.
How to Claim the Offer
To claim your free burger, simply sign up via the QR code in-store or register online at shakeshack.co.uk/halloween-smokeshack-bogof.
Once you’ve got your exclusive code, head to your nearest participating Shack and order through the kiosk for dine-in or takeaway.
Offer valid only on 31st October 2025
