Food porn!

3 of my friends from Nigeria, Kazakhstan and the US and I are coming down to Hyderabad for a couple of weeks. I've never been around Hyderabad even though i was born and brought up there, spent most of my late teens and adult life outside Hyderabad and don't know a lot of places to eat and in general, can y'all suggest some street food places/nightlife life/ parks/ museum, history and of course the BIRYANI! We had biryani from Pakistan, Turkey, Lebanon but nothing came close to Hyderabadi biryani. YouTube is an ocean and can't sail there i know that the best pirates are here and know how to sail!
