Place des Vosges
Start at Place des Vosges, the oldest planned square in Paris (1612), with perfectly symmetrical red-brick façades and a covered arcade running the whole way round. It's a postcard-quiet place to sit on a bench with two coffees before the day opens up; the arcades stay dry if it drizzles, and the lanes spilling out of the square — antique shops, galleries, tiny cafés — are made for aimless, hand-in-hand wandering. Logistics: an easy morning on foot; budget 1.5–2 hours of slow strolling, no tickets needed.
Lunch — Marché des Enfants Rouges. A 10-minute walk north, Marché des Enfants Rouges is the city's oldest covered market (1628) — a warren of food stalls under slate roofs where you each grab something different and share standing or perched. It's casual, atmospheric, and the opposite of a stuffy lunch reservation. Logistics: closed one day a week — check before you go; arrive before the midday rush for a seat, and see the backup below.
