Being a Delhiite, its impossible to avoid Chhole Bhature. Every single citizen of the city would have his/her favorite outlet for the same.
When we talk about Nagpal from Amar colony, we are talking about top of league here. In a city which has a (or two) Cholle Bhature waala at very corner, Nagpal would feature in Top 5 of any self respecting food lover. For some it might be number one, for some number 5, but it has to be there, because they hardly do better than him.
Its not hard to find, just go in Amar colony and ask anyone, and you will be directed to the outlet. The prices are average at Rs.30 per plate. There are other things on the menu too like, Rajma Rice, Shahi Paneer rice etc.
The stuff is pretty heavy, a foodie like me is satiated with two bhaturas itself. If going there on weekend, be prepared to brave some crowds. Generally the stuff sells out by 2 pm.
