I hate that I don't live in Squirrel Hill anymore to walk to this place once a week. When you live in or around the Squirrel Hill area, you are asked to answer one simple question; Aiello's or Mineo's. I choose Aiello's, though Mineo's is pretty damn good too. It's something about Aiello's sauce that puts it over the top for me. I've never had a better local pizza in Pittsburgh. The staff are pretty friendly, especially if you frequent their shop often. There's specialty pizzas, pizza by the slice, hoagies, desserts, salads and other items. It is a little on the pricey side especially for the specialty pizzas. When I ordered the Margherita pizza once, the owner discussed with me how he only uses locally grown produce for his pizza toppings. Locally used produce, owned and delicious....that's my style!
