In some reputed hotels in Hyderabad beef is being mixed in mutton biryani I am told. Is it true?
Never heard of this practice. Doubtful, though. You may, however, ask before you order.
I dont think any restaurant of repute would do it.
Few of the best
Savri, Paradise, Hyderabad House, Golconda, Deccan Orchid, Sohail Hotel, Four Seasons, Mandar etc
