Tahliah Street is a popular attraction among youngsters since 2004,[5] especially when the Saudi government introduced free Wi-Fi scheme in the avenue following its renovation by Omrania and Associates.

The street began to lose its status of a preferred leisure destination by 2019 as a result of the emergence of new entertainment centers in Riyadh under Saudi Vision 2030.
