Sandwiches are suffering an overall decline in sales, but are still a top lunch choice, according to the latest out-of-home lunch figures from international market research company, NPD Group.

Speaking at the recent Lunch! show at Old Billingsgate, London, Sarah Wittenborn of NPD Group said that the bakery sector had a 6.9% share of the foodservice lunchtime traffic, for the six months to June 2009, with average customer spend around £2.40.

The figures showed that 17% of lunchtime orders included a meat sandwich (data for six months ended June 2009), down 0.9% compared to last year, but still topping the table for the most popular lunchtime buy.

Lunchtime purchases including cake fell by 0.7% to 2.8%.
