San Francisco--Pizza chains have taken an early lead among U.S. restaurants that are experimenting with Web-based ordering. Papa John's has developed Web-based ordering technology in-house, and now all 2,700 of its domestic retail locations offer online ordering to all their customers. Some franchisees of Pizza Hut and Domino's are working with Food.com, a provider of Web ordering systems.

According to industry experts, pizza chains are a good match for Web-ordering services because of their experience in providing convenience and delivering a product that travels well. -CBS MarketWatch
