I don't know about the others, but the Azad Hind Dhaba on Purnadas Road sells absolutely bad, dry, fibrous and tasteless chicken kebabs. The Biriyani too is very sad (if you have had good biriyani you can't help noticing the difference).
Plus, they payed me 100 rupee less than they were supposed to. I did not notice then, since I was in a hurry. My mistake I know. But bad food experience. I loved their mutton dopiaza at one point. Not sure about now.
