Best casting, perfect dialogues, super acting by all actors. Introduction of characters like chatrangi bhaiyya with his dubious background, sub inspector pinky with his constable mangi ram, hair dresser chhotte with his unique massage style, tyagi the one who slips in bansal's shop occasionally for a nap, and many more as these, add tremendous flavour to the main cast. A true mix of various facets of personalities from old delhi clearly depicted by the director. Hats off to the entire team.
