I was in Iran in January - very friendly & generous people. The ones that do not have religeon too badly don't like their government much - but they realise it is very difficult to change their government much...that said they dislike the governments of countries that impose sanctions more than they dislike their government.
You can not get any alcohol, especially not 55% proof Armenian vodka that tastes like the sweetest grappa as it is distilled from dried fruits....that is totally forbidden....
