Normally any food left at the end of service is thrown away. Now to try and cut food waste you can pre-book "magic bags" for £2.79 through the Too Good to Go app. This will give around £7 worth of food from what's left at the end of the day.
It's a great way of reducing food waste and a cheap way of getting a meal if you can wait until the end of the service.
There are also lots of places signed up to this in the UK, you can find more information on the Too Good to Go website.
