Once the haunt of expat artists, poets, and dreamers, Antico Caffè Greco, on Rome’s glamorous Via Condotti, is a must. At this 18th-century caffè, you’ll learn that Romans can be very particular about their coffee. Cappuccino is a morning-only affair, and you’ll drink your first one of the day standing up at the bar. When the afternoon slump rolls around, you can sit and savor a caffè macchiato. Open since 1760, Antico Caffè Greco has preserved all of its old-school Renaissance charm. The coffee will cost you five times as much as what you may be accustomed to, but the experience is worth it.
