Restaurants with children
Spanish dining culture is tolerant of children to a degree that surprises most visitors, and eating early makes it easier still.
Eat at local hours
Arriving at eight rather than half past nine gets you the first sitting, more attention from the staff and a calmer room.
Half portions
Most neighbourhood restaurants will serve a media ración or a simple plate for a child; ask without embarrassment.
Reliable formats
Market cafés, counter-service cervecerías and the churros-and-chocolate institutions are all low-friction with small children.
