C’mon. Do it — Explore a bit North of the river and the Louvre, where the streets get less touristy: This is where lies the authentic heart of the Second district. Dress the part and alight upon these refined shopping streets: Place des Victoires (and the little enclave just north of it by the church), Rue de Richelieu, Rue du Mail, rue Vivienne, and Rue des Petits-Champs. Or these beautiful covered passages: Galerie Vivienne, Galerie Colbert, Passage Choiseul, and Passage des Panoramas. Indulge on noodle soup and Asian sweets on Rue Sainte-Anne, an authentic Japanese enclave.
