Yes,I mean he is always boosting their confidence,motivating the contestant who feel low,he is very sensitive,simple,nice human being ,NOT that others are bad but he tops among these 3 chefs for me.You should see his shy smile,its adorable.
I find Sanjeev Kapoor scary esp his expressions when he tastes the food..Vikas is nice ..bt its Kunal who Is my fav ..he is always at ease..never over does anything.
