A Mount Albert Chinese restaurant, known for its duck blood and beef tripe in hot chilli oil dish, has been badly damaged after fire broke out at about 11.30pm on Saturday night.
A Fire and Emergency spokesman said the fire was well-involved when fire appliances arrived at the scene.
"We've had a fire at the Chinese Restaurant ... the fire involving the roof of the restaurant spread to Pizza Hut (next door)," the spokesman, who was at the scene, told media.
"We're not treating it as suspicious, however, we will be working with a fire investigator."
