Staying at Richard's Town(beside Frazer Town).
I go via bus 123 in the morning. 15min bus journey + 15min walk.
In the evening I take the metro to M.G.Road, then bus to ShivajiNagar and from there another bus. Since the 123 bus is very less in frequency, I cannot use it to return home in the evening. So have to travel a lot in the evening.
Sorry to disappoint you. I took the train in the evening yesterday and since it‘s the next stop, got off in just 7mins. Then a small walk and I am home in just 15mins in the evening.
