New Delhi is the capital of India. It is the second largest city in India.
There are lot of heritage and historic place that must to be visited like,
Red Fort, Quatab Minar, Jantar Mantar, Lotus Temple etc.,
This city is very expensive for live, specially for rent charges of fat / home.
The food was very cheaper and tasty.
Central Delhi is very organised and has a lot of historical sites, hotels, restaurants etc.
At some places I have seen people taking drugs in public places, even in parks
So be safe in these places
This city face very much pollution smoke environment which is very harmful.
There are some great malls in this city where you can go to hang out.
Like Select City walk mall which is located in Saket, and Pacific Mall in Subash Nagar.
In General, Delhi is the ideal place for tourism
