Among the dozens of pizza parlors in Pittsburgh that churn out mediocre product, Pizza Sola stands out. It isn't the absolute best pizza I have ever had. It is, however, consistent, good, and uses quality ingredients. Also the crust isn't the ubiquitous thickness of mid western style pizza.
After four different visits to Sola I doubt that I will go to any other pizza place in Pittsburgh. My favorite is the margarita: fresh cheese, good helpings of sauce, not too much salt, and nice fresh basil.
Additional pluses: craft sodas, fast service, and friendly staff.
