Iranian hospitality etiquette
Hospitality, mehmun-navazi, is a point of pride in Iranian culture, and guests have a few gentle responsibilities too.
The Persian word for hospitality, mehmun-navazi مهماننوازی, literally means "guest-caressing." Hosts often go to remarkable lengths, and a thoughtful guest meets that warmth halfway.
At the door
It is customary to remove your shoes when entering a home. Bringing a small gift, shirini شیرینی (pastries) or gol گل (flowers), is a warm gesture, though hosts will insist you "shouldn't have."
The food will keep coming
Expect to be offered far more than you can eat. Because of tarof, a first "no thank you" may be treated as politeness rather than a real refusal, so a gentle, repeated decline is normal when you are truly full.
Words that earn smiles
Praise the food with dastetun dard nakone (thank you for your effort) and kheyli khoshmaze bood (it was delicious). Acknowledge the host's work, and you honour the heart of mehmun-navazi.
Shoes off, a small gift in hand, and a warm awareness of tarof: those three habits make you a guest any Iranian host is glad to welcome back.
