Recommend Good restuarants for best Vegetable Biryani

It's very hard to find good restuarants for biryani especially different kinds of good vegetable biryani or pulao like Brinjal biryani or Vangi bath for vegetarians in Hyderabad. I'm bored with same veg biryani & veg pulao in every resturant I go. Let me know if anyone knows or finds good restuarants & hotels for vegetarians.
