Caley's Marching Chocolate helped sustain troops on the frontline during World War One and the brand continues to support members of the armed forces to this day.

And throughout this month Caley's Cocoa Cafe at Norwich's Guildhall is paying tribute to those who served in both the world wars.

And throughout this month Caley's Cocoa Cafe at Norwich's Guildhall is paying tribute to those who served in both the world wars.

'It is all about commemorating the sacrifices that the men and women of both the First and Second World War made so that we have the freedom we have got today,' said Roger King, a former director of Caley's and who is now semi-retired.

'We have quite a lot of servicemen from the Second World War who come to the cafe and we wanted to do something to say thank you.'

Patriotic Union flags adorn the cafe, part of a World War One trench has been recreated inside the venue, and World War Two posters promoting mottos such as 'make do and mend' and reminding people that 'loose lips might sink ships' are displayed throughout.

Dame Vera Lynn can be heard singing classics such as The White Cliffs of Dover, while cafe staff in 1940s dress serve up a wartime-inspired menu.

With the options displayed on a ration book, people can choose from everything from Spam sandwich with black market piccalilli to cheese and potato pie, and tuck into salad 'grown on the home front.'

Jelly is among the options for dessert and people can, of course, also enjoy a bar of Caley's famous Marching Chocolate.

Cafe manager Dawn King came up with the idea for giving the cafe a world war theme throughout August.

She said: 'We have had a brilliant reaction from people. We have had some people ask us to keep the display permanently.'

Caley's is also continuing its link with the armed services in the present day by selling a special Heroes bar which raises funds for the charity Help for Heroes. Five pence from the sale of each Caley's Heroes bar is donated to the charity which provides support to wounded servicemen and women.
