Green Bawarchi Restaurant in Gachibowli is one of the best biryani point. It has an AC dinning section in the first floor and a general dinning section in the ground floor. Chicken Biryani and Butter Chicken are the best dishes you can have there.
Mutton biryani doesn't taste good there. Chicken Tika and various other chicken related dishes are very spicy and delicious. Veg iteams are even good. Sweets like Gulab Jamun taste very nice. Serving is also a good service.
