Whereever u go u will ask someone a place which is famous in that location. Likely in hyderabad one of such pkace is gokul chat located in koti near womens college. There we will get all chat items at affordable cost and the taste will be superb. I ate twice when I visited koti. U can understand the prominence of it if u remember that a bomb blast has occured there. Bomb blasts will take place mostly in public areas.
