Named after Unione Sportiva, a popular soccer team from Palermo, Sicily, U.S. Original Restaurant in North Beach has been serving guests for over twenty years. A favorite appetizer, the Antipasti de Mare with clams, mussels, shrimp, baby calamari, and scallops on a bed of ice cold lettuce with capers, celery, minced red onion, and tomato served with lemon wedges and a light red wine vinaigrette will whet the appetite for the main course. Daily specials abound, and the Osso Bucco, served on Saturdays, has some locals claiming it to be the best in San Francisco. Open for lunch and dinner seven days a week, U.S. Original Restaurant is a great choice for a casual night out.
