Ladies and female contestants are cordially requested to observe local dressing code as to cover their head with a headscarf and wear loose-fitting long clothing. It is also recommended that men avoid wearing shorts in public.

Local Customs

Shaking hands or other physical contacts between two people of opposite genders is not common, unless both people are from the same family. If you try to shake hand with a person of different gender and she or he does not respond, it is absolutely not a sign of disrespect. Iranians are very respectful to the guests from all countries, genders, cultures, and religions.


Tap water is safe to drink in Tehran. However, it is recommended that those not used to it, drink mineral water instead. Moreover, all alcoholic drinks are forbidden in Iran.


The good news is that Iranian cuisine is superb. Fragrant rice (berenj) is the staple of Iranian food. Boiled and then steamed, it is often colored with saffron or flavored with a variety of spices. When served plain as an accompaniment, it is known as chelo. The two most common meat/chelo combinations are kebab variations (chelo kabāb) or rotisserie chicken (chelo morgh). The variety of options for vegetarians is less. Falafels and garden salads (sālād-e-fasl) and greengrocers are common. Most ash varieties are meat-free and filling, as are most variations of kookoo, the Iranian take on the frittata.
