We returned for another meal excited by our visit last week, and, regrettably, must report that the Margherita pizza underwent a major change in preparation and in taste. For unknown reasons, the restaurant changed its mozzarella. No longer did Stella use the traditional buffalo mozzarella, but, inexplicably changed to the local mozzarella! It made the pizza much drier and the bubbles were absent and the pizza was dry. The pizza was crisp, for those who like it that way, but it lost its authenticity and its Neapolitan character that so impressed us on our first visit. This experience made it clear that Stella is not serious about brining Philadelphia its first true pizza experience. The pizza bianca was still good that was served with the prosciutto as was the fresh ricotta. The gelato remained attractive and inspirational, especially the ricotta gelato. This time we tried a Lambrusco, which was excellent, but priced like a Barolo!
