I have just been once to GVK one Hyderabad and immediately after the visit, I merely got a whole glimpse of what it was going to be.
The best part of the mall was definitely the food court which was in a floor clubbed with inox where one gets to find all the top notch foods including the famed BurgerKing, Pizzahut, Baskins Robbins, Papa Johns etc which collectively makes it a good place to eat.
However, the shopping arena seemed to take a bit of hype as everything was so pricey that a common man couldnt afford.
On the whole, it was just for the ones who visit there for food and shopping isnt very reliable there.
