I am sorry, this tip is not a 100% accurate. The other exit is actually far more easier especially during peak hours. The 5th main which is diagonally opposite the back entrance takes you directly to Malleshwaram and other localities in no more than 7-10 mins. Its not a busy road and has no signal and hence no congestion. The other exit BTW would lead you to central, Mantri mall and Malleswaram circle which are chock a blocked in the peak hours. Any localite would suggest you to avoid taking this this route in peak hours.
