The short clip, which was posted on their Facebook page, explains how customers can 'pay it forward' and help to ensure a homeless person can enjoy Christmas Dinner thanks to their efforts.
A spokesperson for Social Bite said: "We will be opening our doors this year on Christmas Day and Christmas Eve exclusively for homeless people right across Scotland. Our founders Josh and Alice will be in Edinburgh serving a Christmas dinner with all of the trimmings for those with nowhere else to be, and our Glasgow and Aberdeen teams are doing the same there.
The campaign, which the social enterprise promote every year around the festive season, allows Scots to donate a Christmas Dinner live on Itison:
Those who donate can also support Social Bite's brilliant project to build a village for the homeless; through this, the company plan to create a solution to homelessness that spans housing and support right through to employment, creating what they say will be a "blueprint to end homelessness for good".
It's a great cause and a wonderful way to give something to people who truly need it this Christmas.
