I live in South County so rarely make it to Providence anymore. I have very fond memories of Caserta on the hill. There is a joint in my town that used to be called Martino's that had in my opinion a great version of Neopolitan style pizza (They had a brick oven). Now it is Junction pizza with a standard commercial pizza oven, although it is still very good and almost indistinguishable from Martino's version (owned by a former Martinos cook). Anyhow, I have not found any other in the state that compares to this style pizza. I have not eaten in the Providence area (pizza that is) in a long time so I may be wrong.
