Originally from a small town called Decollatura in Calabria, Domenico Petrone and his brother Paolo immigrated to New York with their family in 1966. With only a high school education, Domenico went directly into the restaurant business starting as a busboy, and later he became a waiter.

In 1980, the brothers moved to Marin with dreams of opening an authentic Italian restaurant. The dream came true in 1981 when they opened a restaurant at 22 Miller that had been Davood’s, a successful Persian restaurant since 1973.  The owner had quit after his application for a hard liquor license was denied. In 1991, the Petrone brothers decided to renovate the restaurant to create a lively, upscale trattoria. The restaurant now offers two outdoor garden patios, a wood-burning pizza oven, a full service bar, a front dining room with a view of the plaza (piazza) across the street, and a back dining room with a fireplace. Domenico and Paolo Petrone are currently also involved in three Marin hotels with partners Ray and Patience Zambrano: the cozy Mill Valley Inn located around the corner from Piazza D’Angelo, the 23-room Waters Edge Hotel in Tiburon, and the 50-room Acqua Hotel in Mill Valley.
