The number of meals sold in the first two weeks of December has tripled from around 90k three years ago, to around 272,000 in 2014.
A survey conducted by the company also found that 65 per cent of consumers said that they would be having two or more Christmas dinners during December, with seven per cent claiming that they would have five or more.
Catriona Kempston, marketing director at Mitchells & Butlers, said that people have more than one Christmas to share and celebrate with friends.
“Whilst carving the turkey on the 25th is seen as tradition, our survey shows that in actual fact, more of us are having more than one Christmas dinner as a result of catching up with friends and relatives at their local Harvester or Ember Inns, festive parties at All Bar One and even as part of a Christmas shopping trip when taking a break at Browns.
“One of the reasons for this is the simple convenience of eating out. Not having to worry about cooking means that people have one less thing to think about – making the prospect of having Christmas dinner out much more appealing.”
