One of Naples' best (and best-loved) coffee bars – even the local cops stop by for a quick pick-me-up – is a retro-tastic combo of old-school baristas, an orange espresso machine and velvety, full-flavoured caffè. The espresso is served zuccherato (sweetened), so request it amaro if you fancy a bitter hit.
For an in-the-know treat, request a harem con panna (an Arabica bean espresso topped with luscious cream and devoured with a teaspoon).
There's another branch at Piazza Garibaldi 72.
