If it’s Italy, it has to be espresso. But not every espresso is equal. The perfect cup should have a caramel-colored crema layer on top that is thick enough to support a spoonful of sugar for a few seconds before breaking.

Do in Rome As the Romans Do: Gulp down your espresso in one shot while standing at the bar. If you sit at a table, you will have to shell out you up to four times more than standing.

Experts claim you can find Rome’s best espresso near the  Pantheon, where water is sourced from springs by the Aqua-Virgo, an aqueduct built in 19 B.C. The most popular with locals is at Caffe Sant’Eustachio, where Romans have been stepping up to the stainless-steel bar since 1938 for their morning brew.
