Al42 by Pasta Chef Rione Monti is a pasta restaurant in Rome's Rione Monti district. It serves bolognese, carbonara, and porcini fettuccine, with fresh noodles that have a chewy texture like kalguksu. People waited starting 15 minutes before opening, and a long line formed afterward. The carbonara is on the salty side, so the staff explain the saltiness before ordering.
