An evening walk in Alwarpet and a Masala Tea in RainTree TTK Road is an awesome experience.
I often visit here with friends and peers for a hangout or some serious discussions too, as the staffs read you so quickly and will take utmost care to make you feel as if you stay in your own place / home and seldom intervene, that too when you need them.
I must admit that is something that is very rarely seen in Chennai. I simply love this lounge and their staff.
