Sheffield museum bosses have pledged to improve their packed lunches after rating poorly in a national survey.
The Millennium Gallery scored just 54 out of 150 in a poll by The Soil Association designed to rate the nutrition of meals at top UK attractions.
Secret diners for the 'Out To Lunch' survey complained that children's lunchboxes at the Millennium Gallery Café did not include any veg or salad options.
But they did praise the farm-assured meat and free range eggs on offer.
The gallery ranked seventh out of 20 attractions. Top was the Eden Project in Cornwall with 99 out of 100, while the Natural History Museum in London and Brighton Pier were joint last with a score of 22.
The Millennium Gallery is run by Museums Sheffield. Chief executive Kim Streets said: "The Out to Lunch survey is a great asset in helping us identify our successes and areas for improvement as we work to provide a quality experience for customers at the Millennium Gallery Café.
"We’re pleased to be have been commended for our use of farm assured meat and free range eggs, and for offering child options of selected adult meal and providing children’s cutlery.
"While it’s good to be placed well into the top half of attractions surveyed, the feedback we’ve received will help us provide an even better service as we work towards a top five ranking in the 2018 survey."
