^Nah... I don't think it has any connection with ISKCON.

Akshardham Gandhinagar in Gandhinagar, Gujarat is the sister complex of Delhi Akshardham. The monument in Gandhinagar was also constructed by BAPS. Opened in 1992 amid fanfare, Akshardham Gandhinagar comprises a monument, exhibition halls, a vast colonnade, contemplative gardens, and a restaurant, much like the monument in New Delhi. The architecture and carvings of the monument in Delhi resemble those of the monument in Gandhinagar.
Akshardham Gandhinagar has attracted millions of visitors from across the world, including Bill Clinton who commented, "Akshardham is not only a unique place in India but in the whole world. It is even more beautiful than what I had imagined. Taj Mahal is definitely beautiful, but this place, along with beauty, has a beautiful message.
