Mac 'n' cheese has become a British favourite on eating-out menus, with businesses adding their own spin on the dish, according to figures from a Horizons survey.
Menu analysis shows the dish has been created using classic ingredients to more premium ones and some with the addition of crunchy toppings.
Other places are serving it inside burgers, calzones or as a side dish, which costs between £2.39 and £3.75.
As much as £9.25
However, for a main course, customers are spending as little as £5.95 or as much as £9.25, according to research group Horizons.
Analyst Nicola Knight said: "Macaroni cheese was once a cheap, comfort food for home cooking but has now become a favourite on menus. It's a huge success story for restaurants and pubs and shows that chefs have returned to some of our old favourites by giving them a new twist with modern ingredients.

"Macaroni cheese featured in Mrs Beeton's Victorian cookery books, but its reinvention in the US as mac 'n' cheese gave it a new life in the UK, bringing the dish to an audience of younger diners. Operators love it because it's cheap, quick and easy to produce, offering good margins and is easily revamped with the addition of other ingredients."
