Who doesn't love pizza? There are many versions of a good pizza and coming from South Philadelphia, and being of Italian descent, I think I can claim some semblance of being an expert in this area.
My favorite restaurant in the area as I've mentioned ad nauseum is Limoncello. They have several really good pizzas there. My friend Leann's favorite here is The Carne Pizza, or as I like to call it, the cholesterol lover's pizza. It has sausage, pepperoni, meatballs and salami Toscana. They make a really good upside down pizza, where the mozzarella is under the tomato sauce. (I'm using sauce here to refer to pizza gravy so as not to confuse the uninitiated). Another friend prefers their Margherita Pizza, which is tomato sauce with fresh mozzarella and basil. All of these pizzas are very good. There are 11 other choices and I'm sure there is something for every palette. You can access their menu here.
If you are looking for a cold tomato pie, I'd go to Carlino's. Their pie is chunky tomatoes and you can also have it Margherita style with fresh mozzarella. It's great for an appetizer because you serve it at room temperature.
Pica's in West Chester is another favorite pizza. They also put the cheese under the sauce and I'm told they use mild provolone instead of mozzarella but I have never been able to verify it. They also have a location in Upper Darby.
There are many other great pizza places in the area. Go out tonight and try one!
