Sant' Eustachio Il Caffè
The line at the Sant' Eustachio Il Caffè is almost as long as the one at the nearby Pantheon, but it moves fast. Pay first at the register if you want a quick coffee standing at the bar, or sit down at a table outside and order a monachella, a fancy coffee drink that has layers of sweetened espresso, hot chocolate, and whipped cream. That seat is going to cost extra, but it comes with a view of a 16th-century fresco, a swirly Borromini spire, and politicians in expensive suits on a break from the nearby Senate. If you’re looking for wifi and a big salad for lunch, the same team has Emporio Sant’Eustachio, Rome’s more stylish answer to Starbucks, around the corner.
