We ate there for lunch and were very happy with the offered buffet. You can eat as much as you want for a very moderate price. Dishes with yogourt and ghee are well specified so you can easily eat vegan. There is no vegan desserts but you'll have a lot of fruit choices. Food is of good quality and the place is pleasant even if it could be crowded.
Highly recommended in Hyderabad.
Cons: sometimes crowded
