| You may admire both the romantic love story and the mysterious city of Rome in the movie Roman Holiday. If you are planning to visit Rome, here are some cultural dos and don'ts you should know. Coffee Etiquette: Italian breakfast consists of pastry and a cup of Cappuccino or shot of espresso. Cappuccino is a morning drink and is not drunk after noon by real Italians. A post-dinner espresso, however, is a common practice. Dinner rules: Guests are expected to arrive for dinner reservations at least fifteen minutes late. In many restaurants, the printed memus are only for tourists. Regular customers know how to ask for the daily specials, which typically feature the freshest ingredients. Bread is rarely served together with butter or olive oil. Drinking water. Rome has plenty of public water fountains, and real Romans (and their dogs) always drink directly from them. Many people also refill their water bottles from these fountains. Mind the traffic: Unless there is a traffic light, or you are in a crosswalk, don't expect cars to stop for you. Though crosswalks go first, in a car-crazy city, still you'd better keep cautious and walk cautiously. Money: Always have some Euros with you. Most major hotels, restaurants and shops take credit cards, but many smaller operations will either be unwilling to accept them for smaller purchase or not accept them at all. ATMs are available throughout the city and at the airports. About soccer: Most Italian men are passionate about their soccer. Arm yourself with some knowledge of Italy's soccer scene, and you will find ready conversation partners almost everywhere. The Romans: The people here love to share their thoughts, opinions and emotions. They are creative, passionate, playful, occasionally rude or vain but always entertaining, and almost always good-humored. | ||||||||||||
