Want a really quick meal go to aao khao, is a small sized restaurant which is located near by the ORR circle gachibowli, with max capacity of 20 people, which is I believe fine enough since they are engaged in Home delivery which I heard is quite fast.
They have a small menu with starters, main course n deserts. This is one of the best places in Hyderabad to have the butter chicken, which is very much authentic and close to the original one.
The chicken roti combo with sweet lassi is awesome. The bhaturas at this place are soft and one of the best i have had. Good self service food joint and with pretty reasonable pricing, enough to earn customer satisfaction as quality and taste are overwhelming
