As the name refers it is a book cafe. But I think it can also be visited even if you are not so much into reading as you can spent as much time as you want over there and work.
No high profile interior, classy look or expensive food but a really amazing place to just stay with your friends do your work and have food. It is also the place people would think to visit if they want to spent some time in solitude. The food and service is nice. For me waari book cafe was the best experience in terms of cafes in pune.
