Cultural Tip
In Brazil, it’s customary for waitstaff to ask this question even if the menu only lists ‘água’. Most households keep both still and sparkling water on hand, and many people have a strong preference. In Portugal, sparkling water (água com gás) is more common, so you’ll often hear the question phrased as ‘Água com gás ou sem gás?’
