Visiting Hyderabad next week.. Please suggest some good places to try the famous hyderabadi dishes!!

Hello Guys!!! I am from Kochi, Kerala and is travelling to Hyderabad for my this years road trip next week. It's a 7 day trip although 2 days each to and back goes in travel. I will be reaching Hyderabad on monday and is staying near Gachibowli - intentionally away from Hyderabad city. I have three full days in Hyderabad to see as much as I could. These are the places I am planning - A full day at Ramoji Film City, Golconda fort, Qutub Shahi Tombs, Salar Jung Museum, Chow Mahalla Palace, Char Minar, Lumbini park. Not sure if any more places can be covered with the time I have. If any other good places are nearby, please suggest.

I have heard a lot about the food culture of Hyderabad. When I tell anyone I know about my trip, first they ask is "Is it a food tour?". So I really want to experience the food of Hyderabad. But I really don't know much about it other than the extremely famous Hyderbadi Biriyani and Irani tea. Please suggest some good dishes decent places (quality and hygiene) I can find them. I am travelling with family including a toddler, so would like safe and hygienic places. It will be good if I can find food places near tourist places I am visiting. If it is not that possible, I will try to make some time for visiting food areas.

What else should I look for? Heard Char minar area can be a bit risky. Is it true? How can I ensure safety when visiting such crowded areas? Any other recommendations are welcome.. Thank you!!
