Buy a book and start reading it on the spot, over some tea and cakes. Oxford Bookstore has a collection of books to please every bookworm. Afterwards you can head straight upstairs to Cha Bar to read and write at leisure, while relishing what is probably the biggest range of teas in Kolkata {including a variety of tea-based mocktails}. They have also got coffee, shakes, lassis, sandwiches, pasta, brownies and cakes.
