Pi Day is celebrated on March 14th (3-14) around the world. Celebrate the Castle Hills way with a trip to PI.E 3.14 Everyday Eatery at the Village Shops. For the occasion, we recommend The PIE, with pepperoni, pepperoni and…more pepperoni; the classic Margherita; or the spicy Pollo en Fuego. So many options for celebrating Pi Day! Enjoy!
