The business was founded by Peter Boizot in 1965, when he opened the first restaurant in Wardour Street, London. The chain expanded, initially as a franchise operation. In 1993 the company was brought to the London Stock Exchange by way of a reverse into a small shell company organised by Luke Johnson, Hugh Osmond and David Page.
They expanded the company both organically and by buying in the franchisees. By 2003 there were more than 300 restaurants in the UK, as well as outlets in Ireland, where it trades as Milano, and Spain and France where the brand name is Pizza Milano. In other countries the business is branded as Pizza Marzano.
