Clark Freeport & Angeles City
C' Italian Dining (1210 Don Juico Avenue, Angeles City; +63 45 8924059) is known for the panizza. C' Italian Dining had already been serving these sumptuous pizzas rolled with arugula and alfalfa long before Yellow Cab came out with Dear Darla. And there's no way you can compare the taste! The C' panizza is the best!
The best sellers are Don Carmelo: spicy chorizo, anchovies, thyme and pecorino cheese; Kristina: bacon, ham, caramelized onion, sun dried tomatoes and mushrooms; and Saint Jacques: scallop flakes, shrimp, sun dried tomatoes and chili flakes.
Historic Camalig Restaurant (292 Sto. Rosario Street, Angeles City; +63 45 3225641 or 8881077) is the home of Armando's Pizza. My personal favorite is Doy's Kapampangan: longganisa, ebun buru (salted duck egg), onion & pickle relish. Their newest offering is Marco's 3-Way: sun-dried tomatoes & kesong puti plus a choice of either tuyo, tinapa or chicken adobo. Then there's Mexican Medley: shredded chicken breast (sauteed in hot pepper & pizza sauce), fresh tomato & spring onion. Another personal favorite is the classic Armando's Best: same toppings as All The Way, but with extra peperoni, double ground beef, double green pepper, double mushroom & extra Canadian bacon.
Didi's Pizza (MacArthur Highway, Balibago, Angeles City; + 63 45 8921184) serves a very Filipino-flavored pizza if you know what I mean. My personal favorite is the Combination: mushroom, salami, pepperoni, green pepper and onions.
Salvatore's Ristorante (300 Fields Avenue, Balibago, Angeles City; +63 45 8920484) serves good Italian pizza as well. Their best seller is Italian De Luxe: salami, pepperoni, Italian sausage, mushroom, green bell pepper, onion, black olives. While the toppings of Italian De Luxe are mixed together, another flavor called Combination has Vegetarian on one side, and Meat Lovers on the other half.

Olives Restaurant (Thunderbird Resort, Poro Point, La Union; +63 72 8887777) serves delicious wood-fired pizzas. Their best seller is Four Cheese: goat, parmesan, feta and mozzarella cheese. My personal favorite is Quattro Stagioni: kalamata olives, artichoke hearts, parma ham, fresh mushrooms. Also try the Spicy Sausage, Roasted Peppers, Mozarrella & Oregano Pizza or the Smoked Salmon & Mushroom Pizza: smoked salmon, fresh mushrooms, tomato sprinkled with oregano and cheese.

Casa Napoli (Abad Street, Brgy. Kaychanarianan, Basco; +63 927 7583370) serves pizzas with mozzarella cheese all the way in Batanes. Nothing really fancy about the pizzas but being in Basco, it's a novelty.
I'm sure there are more such as those in Baguio City, so please list them down by commenting below. I'll try to visit them when I can and add to this list.
