Customs was very smooth. After that we picked up our bags and headed to the exit where our luggage was scanned to ensure we didn't have any alcohol or other contraband items inside. (I was scared that they would deem my Entertainment Weekly magazines inappropriate, but they didn't physically search anything.)
Next we procured a private taxi to take us to Isfahan (about 4 hours away). The taxi driver looked about 15 and sported a jacket with a large D & G (Dolce and Gabbana) on the back. He was also glued to his cell phone a lot of the time!
