Probably the best Guinness Christmas Advert ever:

Guinness are not only famous for their black stout, they produce some of the best blockbuster ads for Christmas on this side of the Atlantic.
With an annual turnover in sales of $6 billion that should come as no big surprise.Still, we can’t but help reminisce about their best Christmas Ad ever circa 2011. I wish one of my favourite streets; Parliament Street, really did look like that in the snow with the Christmas tree slap bang in the middle of the road.
It’s the type of ad that just warms you up inside. Dublin looks cold, cosy and great all at the same time.
