One $50 gift card valid at all Grimaldi's locations in Arizona. IN THE WORLD OF PIZZA...Grimaldi's is an institution. With over 100 years of coal fired brick-oven pizza-making traditions, we continue to ensure that future generations are able to experience our distinctive and truly authentic pizza. Why coal-fired brick ovens? The tantalizing aroma of pizza and calzones baked to perfection in our signature coal burning oven offers a unique flavor and a crisp crust that is just not possible from gas, convection, or wood burning ovens. Our fresh ingredients, handmade mozzarella, 'secret recipe' dough and pizza sauce make us the most award-winning pizzeria in the United States.
