I had no idea Stone has been around for nearly 5 years! This pizza joint is in a superb location (literally steps away from point state park). I think the oven they use to prepare the pizzas produces a high quality dough that nearly recapitulates the chew, toast, and texture of the dough in Naples, Italy. It's probably the closest thing you will find in Pittsburgh to Neopolitan pizza. The only thing that is slightly off is that the dough seemed a bit more closed texture possibly due to the low turnover at the time I was dining there.
I think their pizzas are not quite as satisfying as those at Proper Brick if you're looking for pizza downtown, but they clock in at just half the price. Similarly, you can't beat the outdoor seating views on a summer evening.
