McDonald’s has announced its viral milkshake will be officially coming to the UK - but you’ll have to be quick to get it. The fast-food chain confirmed rumours that the Grimace Shake will be available at selected restaurants around the country are true. For just one week only McDonald’s customers will be able to get their hands on the viral purple drink.

The Grimace Shake will be available to buy from Wednesday, August 28 to Tuesday, September 3 at participating restaurants, through the McDonald’s app, at the Drive-Thru, or via McDelivery. Inspired by the purple character, the Grimace Shake features a blueberry flavoured syrup blended with a creamy milkshake base - the perfect purple combination. The drink will be priced between £2.

69 and £2.99 for either a medium or large, respectively. As McDonald’s UK turns 50 this year, what better way to celebrate than to bring the Grimace Shake to restaurants nationwide.

For McDonald’s fans in or travelling to London on Monday, August 26, they can get their hands on a Grimace Shake early by visiting BoxPark Shoreditch from 12pm-6pm. But hurry once they’re gone, they’re gone. Everyone else will have to wait until August 28 to taste the purple drink.

So fans will have to run, not walk, to score a Grimage Shake. McDonald’s will also be launching a new menu on Wednesday, September 4, including a brand new Twix Latte. Other items making a return include the Philly Cheese Stack, Chicken Big Mac, Mozzarella Dippers, Mozzare.
