‘Caffé’ is what we’d call an espresso. It’s served, not too hot, in a petite espresso cup and saucer, thick, dark and without milk and comes with a complimentary glass of water. You can take your Espresso short (ristretto) or long (lungo) depending whether you like it with more or less hot water. It’s not as diluted as an Americano and more authentic. If you need a proper caffeine hit go for a Caffé Doppio (corsivo) which is simply a double shot espresso.
