Especially in India, stations rarely have a dedicated bookstore and thus having one is no less than a commendable initiative. Being under the aegis of Govt. Of India, this bookstore has books for as cheap as ₹20/- and will only go as high as ₹1500/-
Books on literature, regional stories, folklore, literary pieces etc. donne the shelves of this store. The best thing is you can even get a subscription for the books that you want.
In a nutshell, I believe that in the world where fast food stores crowd the metro stations, these bookstores come as a respite that the world will shrink a little slower.
Look around as soon as you get down the first level of Kashmere Gate Metro Station.
