Got my Iranian visa in Yerevan and crossed overland to Tabriz. Iran is unusual in that ATMs don't accept credit or debit cards,due to western sanctions, you must carry cash. People very friendly and have a real interest and curiosity about the outside world. No drinking of alcohol permitted, that didn't bother me at all. Foreign women tourists must by law wear a shawl to cover their hair. Easy to get around by bus, very inexpensive, and the food is good..
