Meal times in Iran vary considerably from those in Europe and the US. Lunch can be served from 12PM-3PM. and dinner is often eaten after 8PM. These and other social occasions in Iran are often long, drawn-out affairs conducted in a relatively relaxed tempo, often involving pastries, fruit and possibly nuts. As it is considered rude to refuse what is served, visitors should accept the items offered, even if they do not intend to consume them.
The importation and consumption of alcohol is strictly banned. Penalties are severe. Religious minorities, however, are allowed to manufacture and consume alcohol, but not to sell or import it. Pork and pork products are forbidden and, like alcohol, their import is illegal.
The good news for travellers is that Iranian cuisine is superb. A wide range of influences from Central Asia, the Caucasus, Russia, Europe and the Middle East have created a diverse, relatively healthy range of dishes that focus on fresh produce and aromatic herbs. The bad news, however, is that Iranians prefer to eat at home, rather than in restaurants, so decent eateries are scarce and stick to a repetitive selection of dishes mainly kebabs. An invitation to an Iranian home for dinner will be a definite highlight of your stay. When visiting an Iranian household for the first time or on a special occasion it is customary for Iranians to bring a small gift. Flowers, sweets or pastries are popular gift choices.
