The restaurant group credited the ‘wide guest appeal’ of the concept as contributing to a boost in footfall at Crown Carvery restaurants which had introduced the offering.
Sizzling Pizza & Carvery offers diners a choice of stone-baked pizza alongside a carvery, unlimited vegetables, salad bar, sweet shop, ice cream and candy station.
Helen McGregor, operations director for Sizzling Pizza & Carvery, said: “Overseeing the transformation of our Crown Carvery estate into a new Sizzling Pizza & Carvery is a joy to watch, not only from seeing the amazing returns being delivered, but also through the engagement from our teams and guests.
“Every new business is buzzing with excitement and we’re seeing many more new guests join our regulars for a great meal out.”
Upcoming sites set to be converted to the pizza and carvery concept include The Windmill in Denton and The Pig and Whistle in Preston in March, with more locations to follow over the coming months.
Crown Carveries was rated best value for money in a 2014 consumer survey.
But Mitchell's & Butlers has warned that it could raise prices across its restaurant brands following the introduction of the National Living Wage in April.
The company operates over 300 Sizzling pubs across the UK.
