Hemant Mathur, the much celebrated chef of Diwan and Tamarind, quit Diwan, an Indian restaurant on 48th street. He is now working at Amma on 51st street between 2nd and 3rd ave. I called Diwan and they still say that he is on vacation for a couple of weeks. Not true. I saw and met Chef Hemant at this place where he is working for a few weeks now. Good luck to him.
