Decked out in sunny yolk-yellow aprons, Quattro Shot’s staff weave about minimalistic interiors of wood and concrete, softly illuminated by sunbeams streaming through gleaming glass-front doors that also offer up views of Penang’s busy cityscape. Office grunts and caffeine addicts drop in for fortifying sips of the cafe’s signature hand-brewed espressos, while those with more time to spare settle in for light bites, comprising classic favourites like flaky croissant sandwiches, nasi lemak sotong, or creamy bowls of carbonara topped with smoked salmon.
