I had a major Pizza craving today thinking I could easily eat 1/2 pizza. Lol First time I've ordered from them. Such great quality & I was surprised how big the pizza was & they give You a good amount of toppings. I can eat ALOT but was so full ...I ate half the spinach salad which was so so good & 2 1/2 pieces of the pizza! I ordered the 4 topping & added extra olives & green peppers. From other pizza places I can easily eat 1/2 a pizza. The 16" would definitely be enough for 3-4 of me so tasty I highly recommend this place!!!!!
