Pitfire Pizza owner Paul Hibler hinted that rapid expansion was on his mind back in June. This Thursday, his locavore pizza and craft beer concept stretches its wings to Orange County, with the opening of the chainlet's seventh outpost. Opening at 11:00 A.M. on Costa Mesa's 17th Street, this Pitfire will also be the brand's biggest store, taking over an old Marie Callender's with a "Surf City" motif and the concept's signature sight, a rounded, red Mugnaini oven that wood-fires pizzas at 630-degrees. Pitfire's expanded size down south will allow the restaurant to open a private event room, tasting kitchen, and space for pizza classes. Expect a community night on Wednesday evening, open to the public from 5:00 to 10:00 P.M., with 100% of net proceeds going to the Boys and Girls Club of the Harbor Area.
