National Burger Day is observed in the United Kingdom on the Thursday before the August bank holiday, specifically on August 28 in 2025. This unofficial holiday was launched by Mr. Hyde, a daily email service focused on style, culture, and dining. It celebrates one of the most popular meat dishes, the hamburger, which consists of cooked patties placed inside a sliced bun and often accompanied by toppings such as cheese, bacon, lettuce, and various condiments. On this day, participating restaurants across England, Scotland, and Wales offer burgers at a 20 percent discount, encouraging both independent eateries and chains to take part in the festivities. The celebration also includes street food events, with a complete list of participating restaurants available at nationalburgerday.co.uk.
