At the bar
un caffé – will get you an espresso coffee, small and very strong. Add lots of sugar (zucchero)
un caffè macchiato – indicates an espresso coffee with a dash of warm frothy milk, like a mini cappuccino. If you prefer you can ask for cold milk (latte freddo)
un cappuccino – the universal frothy coffee, always made with full cream milk and usually luke warm. Ask for it caldo (hot).
un aperitivo – a ritual pre-lunch or pre-dinner drink. You can have it either alcolico or non-alcolico and leave the rest up to the barman. Good bars serve a variety of snacks to go with it.
