A female onlooker, who wished to remain anonymous, said she felt people were on edge, after recent fires in Jewish establishments in London and Manchester.
Kay’s kosher supermarket, only 150m away, was gutted over the weekend.
An officer told the JC that tonight's incident: "was a fire that broke out in a chip pan at the back of the restaurant, which spread to the roof.
"It was put quickly by fire officers - and thankfully no-one seems to have been hurt."
