MANILA -- California Pizza Kitchen is celebrating National Pizza Day this year by offering a unique buy one-take one promo.

For every pizza bought on August 15 or 16, customers get a limited edition pizza for free. The free pizzas are all-new creations and are not on the regular menu.

One of CPK’s most popular appetizers, Nachos with Spinach and Artichoke Dip, was the inspiration behind the Grilled Chicken and Asparagus on Spinach and Artichoke Sauce Pizza.

Continuing CPK’s fondness for wholesome pizza variants are the duo of the Ham, Mango and Cucumber Pizza, and the vegetarian-friendly Primavera Delight with healthy toppings such as zucchini, broccoli, button mushrooms, carrots and roasted squash puree.

The Pizza Italian, meanwhile, is topped with ham, rustic pepperoni and CPK's flavorful pomodoro sauce.

The last offering, the Cheese Triplets Pizza, is a delight for cheese lovers as it is generously topped with Mozzarella, Queso Quesadilla, and Velveeta.

The winner of the 2017 CPK Pizza Wars, the Garlic Cream Cheese, and Sausage Pizza, will also make its debut appearance in the CPK menu during National Pizza Day. When guests order this pizza, they will also be eligible to receive one of the pizzas listed above.

This year’s National Pizza Day also marks the beginning of the year-round celebrations of CPK’s 20th anniversary in the Philippines, which will be marked with more surprises, and promos from the pizza chain.
