Burger chain Honest Burgers will give away 3,200 free meals across London on Wednesday.
On December 3, the chain will give free meals to the first 100 people to queue up outside their participating restaurants across the UK, 32 of which are in the capital.
Usually £13, Honest Burgers will give each lucky diner a Double Smashed Burger and a portion of rosemary salted chips free of charge.
The burger features two smashed British beef patties, American cheese, brown butter mustard mayo, diced onions, and homemade pickles.
The offer will be on a first-come, first-served basis, with tickets issued to the first 100 people to queue up outside their venues. Winners can either dine-in or takeaway.
Those who narrowly miss the cut will be able to sign up for a £5 voucher to spend in January 2026.
Honest Burgers restaurants open between 10:30am and 11:30am, so you can treat yourself to either an early lunch or a late breakfast - see the full list of participating London restaurants below, along with their opening times.
