* Bob Payton, 50, the American who brought deep dish pizza to Britain and opened 30 restaurants around the world, was killed Wednesday night when his car went off the road near Stevenage, 28 miles north of London, hit a large highway sign and overturned. The Miami native was working for the J. Walter Thompson advertising agency, which transferred him in 1973 to London, where he opened his first restaurant, The Chicago Pizza Pie Factory in 1977. "He loved living in London but what he thought London needed was a Chicago style deep dish pizza. He missed eating them so he opened the restaurant," said Stephen Gee, a former colleague who worked with Mr. Payton for 17 years. In 1982, Mr. Payton opened the Chicago Rib Shack. More restaurants followed until he had 30 restaurants in cities including London, Paris, Tel Aviv, Buenos Aires, Brussels and Barcelo na. Mr. Payton's company, My Kinda Town, went public in May and he sold his interest to focus on Stapleford Park, a 16th century country-house hotel where he lived near Melton Mowbray, 90 miles north of London.
