Cha Bar: This little tea bar is located in one of Kolkatas favourite bookstores. The heavenly combination of tea and books might just make you a permanent fixture in this delightfully cosy tea bar. Tucked away in a nook of the very popular Oxford Book Store, this place is a wonderful addition; full of warm smells and treats to eat. Like sandwiches, tarts and puff pastries. From fragrant cherry, peach and other exotic fruit-flavoured tea to the more milky masala chai, the selection of teas is almost as varied as the books in the store.
