I used to live on Tehran, Iran. All restaurants, stores and businesses must be closed after 12:00 AM in Tehran.
So one night me and a friend were driving around the town in midnight and we were quite hungry. So we found a nice guy selling tea in the winter and there were other people around. We asked them if we can find food anywhere in town in this hour.
One of them gave us an address and told us we should just go there and wait in the car.
We didn't really believe, but we gave it a shot.
I kid you not. At 4:00 AM in the morning, in an alley, we stopped and a sketchy man came over and handed us a menu!
It was fast food. Pizza, burgers and chicken strips. It wasn't really good.
It was a few years ago. Nowadays there are always a few people hanging around and they sometimes open the doors and let people in.
