This is where Francis Ford Coppola wrote “The Godfather.” Makes sense once you’ve experienced the authentic Italian ambience at the Caffe Trieste. Here, “Papa Gianni” opened his first coffee shop in 1956, and initiated Americans in the art of enjoying espressos and cappuccinos. The 92-year-old host is a man of many talents: On Saturdays he grabs the mic and entertains his guests with semi-classical Italian repertory, accompanied by his family and the clatter of coffee cups.
