The food at some of Britain's top tourist attractions has taken a hammering from the Consumers' Association.
The association's latest Which? report has criticised attractions across the country for offering a limited range of healthy options.
Fast-food outlets were the mainstay of most theme parks, it concluded, and "healthier" options were often confined to kebabs and salads.
Fresh fruit and vegetables were hard to find, and when they were available were often unattractive or unappealing.
Which? sent a dietician and nutritionist to visit 20 theme parks between April and May, scoring its restaurants or food outlets on their availability of healthy alternatives.
A score of one meant no healthy choices at all were on offer and five meant there were three or more low-fat choices and at least two portions of fruit and vegetables.
The worst offenders were Camelot in Chorley, Lancashire, Flamingoland in Kirby Misperton, North Yorkshire, and New Pleasurewood Hills in Lowestoft, Suffolk.
But the British Museum, Eden Project and Edinburgh Castle were all congratulated for their efforts to provide healthier alternatives.
The association urged park operators to provide a wider range of affordable and healthy options, including introducing a "traffic light" labelling scheme to highlight healthy eating choices.
Nick Stace, director of campaigns at Which?, said: "Today's research is yet another example of how hard it is to make the healthier choice.
"The industry needs to ensure that wherever you are it's just as easy to pick up a nutritious sandwich and some fruit as a hotdog and fries."
Digby Trout, founder and chairman of digby trout Restaurants, which runs the food operations at Edinburgh Castle and the British Museum, said the findings vindicated his company's commitment to using fresh ingredients.
