Very good architecture and very beautiful place. Love the chandeliers and it has world's largest carpet made by people of Iran. Its entrance is from underground passage then using escalators one would reach the mosque.
The rules for dress code are most important for them. Men should have full covered legs and full covers sleeves. Half sleeves can be considered but for men only. Ladies must have their head covered with full sleeves dress and full sleeves leg dress.
Remember that the way you enter the mosque is the only for exit.
