We have two hard and fast rules for visitors to Italy: 1) Drink as much espresso as you can, and 2) Eat as much pizza and gelato as you can. Sticking to the second rule in Trieste we head straight to Pizzeria di Napoli, a couple of blocks west of the Piazza Unita. They offer up some of the city’s best pizzas cooked to perfection in the wood fired oven and what better way to complete a meal than with espresso (order it correto for a real treat) and gelato.
