Philly’s Italian Market, the oldest and largest working outdoor market in the United States, is a culinary street carnival that covers a six-block radius along Ninth Street, between Wharton and Fitzwater. Eat your way from one end to the other and in between, with definite stops at Paesano’s (1017 S. 9th St., 215.440.0371, paesanosphillystyle.com), a legendary sandwich place—try the Arista, piled high with brisket, horseradish mayo, pepperoncini, provolone and a fried egg. It doesn’t get better than Sarcone’s (734 S. 9th St., 215.922.1717, sarconesdeli.com) Italian hoagies on crusty, house-made rolls; we like the gourmet version with prosciutto and hot sopressatta. After recovering from lunch, head to Sicilian eatery Monsu (901 Christian St., 215.440.0495, monsurestaurant.com) where Peter McAndrews lovingly creates regional dishes like fried rice cake with short-rib ragout, and Sicilian sausage gnocchi flavored with chocolate and cinnamon. Ralph’s (760 S. 9th St., 215.627.6011, ralphsrestaurant.com) wins the prize for staying power, a family-owned fine dining operation since 1900—and yes, the pasta and veal dishes are better than Nonna used to make!
