Start at Piazza del Plebiscito around 3:00, while there’s still good light for photos. Give yourself about 30 minutes to wander the vast square and take in the colonnades of Basilica Reale Pontificia San Francesco da Paola. From here, Gran Caffè Gambrinus is just across the square: settle in for a Neapolitan espresso and pastry, budgeting roughly €5–15 per person and about 45 minutes. It’s a historic, often-busy café, so ordering at the counter is usually quicker than sitting down.
Walk a few minutes to Galleria Umberto I and look up at its glass dome and patterned floor; allow around 30 minutes, and be considerate as people also use the arcade as a through-route. Then stroll down Via Toledo toward the Quartieri Spagnoli for about 45 minutes. The street gets livelier as the evening goes on, with plenty of shopfronts and side streets to peek down—keep an eye on your belongings in the crowds.
Finish at Trattoria da Nennella for generous, informal Neapolitan cooking and a famously raucous atmosphere. Expect roughly €15–25 per person and allow 1–1.5 hours; it can be noisy and busy, so arrive early if you can. Since it’s Sunday, check today’s dinner hours before setting off—opening schedules can vary, and it’s worth confirming rather than finding the door shut.
