• Mornings are best, when the fish counters are fullest; stalls start packing up by early afternoon
• Fish counters on ice where kids can see the morning catch up close, whole fish and all
• Cafés inside the market for a coffee or a snack once the shopping is done

Mercado de Arroios is a municipal food market built in 1942, with stalls set in a ring around a central courtyard under wide concrete arches. Fishmongers lay out the morning catch on ice, and fruit and vegetable stands stack whatever is in season.

Renovated in 2017, it also has cafés and places to eat, so a shopping run can end with a snack.
