In the first installment of its new Case Study series, CSA Online offered an insider’s look at the conception and initial rollout of the southern Calif.-based fast-casual concept PizzaRev. Likened to “the Chipotle of pizza,” this innovative chain lets customers choose from an artisanal array of toppings to craft their own pizzas. Using a 900-degree, stone-hearth oven, pizzas are ready in about three minutes, all at a cost of less than $8 per pie.
