Tony Gemignani, a champion pizza maker and author, is expanding his restaurant business. His Slice House brand is growing, with new locations opening in the San Francisco area and potentially nationwide, and has been recognized as a fast-growing emerging franchise. However, it is unclear if Gemignani is the only world champion pizza maker opening new restaurants in the Bay Area, as reports also mention a female competitor who won a world pizza competition in Italy and is now opening her own restaurant.
