The restaurant, or prison restaurant as the owners call it, has gone so well that they opened two more with the same theme.
All profits go towards freeing prisoners who are incarcerated for their unpaid debts.
The idea came to the owners when an anonymous person paid off their debts.
The restaurant has done so well that they recently opened two more, another one in Teherean and one in Isfahan.
