Awesome family-owned business ! Great pizza, burgers, and the best hoagies this side of the Triangle !!! I've been eating Veltre's since the early 80s and they've only gotten better with time.
Pizza toppings are generous, the sauce is spicy without being overwhelming, and crust is crispy without being burnt. The calzones, sides, burgers, and salads, especially the steak salad, are all also very, very good - I've literally had every single item on the menu and never been disappointed !
Worth noting that the employees there and delivery drivers are always very helpful and friendly, and when you call an order in they're always willing to help with suggestions or substitutions. You can also make special requests that they never shy away from - I've asked for garlic butter on my pizza crust, extra this-or-that, and for a few absolutely crazy pizzas and I've never been disappointed.
Bonus Points: They use Mancini's rolls. As a Pittsburgher that's all I needed to hear.
