On this day in 1979, Dorene Centioli-McTigue opened the doors of the pizzeria Seattle came to know and love as Pagliacci -- which still stands today on the "Ave." Thirty years later, that long-lived store joins its siblings on Lower Queen Anne, Broadway and the UW campus, celebrating that day by throwing back prices on slices and fountain sodas. For today only, Pagliacci is selling cheese-, pepperoni- or a combo-slice for less than a buck, and offering their popular Primo for $1.05 -- just as they did in 1979.

It's been nearly a decade since a trio of savvy Seattle businessmen, Matt Galvin, Pat McCarthy and Pat McDonald, bought what was then a dozen stores selling "Philadelphia-style" pizza. They've since expanded to 21 locations, with delivery-kitchens coming over hot throughout Greater Seattle. To celebrate their continued success, as well as that of a legion of Pagliacci employees -- seen below smiling from a compostable box -- they've instituted a 30-day discount of 30 percent on 17-inch pies, with a limit of one discounted pizza per order (get all the celebratory details right here):
