Almería's Central Market is a handsome everyday market rather than a staged food hall. Fish, fruit, vegetables, cured meats, and bakery stalls fill the building, and the mood is still local enough that you feel like a visitor in a working city, not a consumer in a theme.
Go in the morning, when the stalls are busiest and the fish counters are at their best. It is a good place to get a sense of what the city eats before you choose a tapas bar for lunch.
