Twelve-time World Pizza Champion, cookbook author, and East Bay native Tony Gemignani is inviting Walnut Creek Pizza fans to the official ribbon cutting for Slice House Walnut Creek as a thank you for their support of the business since it’s opening in May of 2016 and to highlight the newly opened patio seating. The event will begin with a few words from Tony at noon and be followed by a ribbon cutting ceremony. Members of the Chamber of Commerce will be in attendance alongside Walnut Creek Mayor Pro Tem Rich Carlston, and Councilwoman Cindy Silva. All attendees will be given a free slice of Sicilian, Grandma, Cheese, Pepperoni, Tomato Pie with Basil or Picante pizza and a complimentary soda.
