It all began in the early 1990s with Mr Donald Duncan,
who spent some time working in a pizza restaurant in Kansas City, Missouri, USA. After spending 5 years in the business, Mr Duncan developed his own recipe of dough, and tomato sauce, also known as the “Duncan Sauce”. Mr Duncan then opened the first outlet in Malaysia in 1997, and named the outlet to US PIZZA, to pay homage to his food origins.
