On any leisurely afternoon, while at MG Road, you would often get some coffee at the India Coffee House. If you were in a mood for some snacks, you could order a dosa or a cutlet.
I only wish ICH stayed on at MG Road. After a Metro ride, some hot coffee would have been great. Of course, you could go to Kohinoor, but one, you really wouldn't and two, for all you know, it may not be there any more.
