I'm a Penn Hills native, and Pasqualino's is a must when considering take-out.
Everything on their menu is delicious. Their pasta sauce is slightly sweet and is great on the stuffed shells (my favorite!), spaghetti and meatballs, and lasagna.
Their pizzas are sicilian (thick cut, square). My family loves their pizza. Frankly, sicilian isn't my pizza preferance. I always order one of the pasta or salad entrees, both of which come with freshly-made rolls and butter.
Staff is friendly, and if you go there enough, they WILL learn your name and food preferences.
Overall, food is cheap and high-quality.
One tiny drawback. They do not deliver. But I do not think that warrants a docked star.
