I ahve been here so many times from my childhood with my family to recently with my friends..This is place is worth visiting

To see the Gateway monument
The taj hotel that is opposite it
To enjoy ferry rides that take you deep in the ocean
To see and feed the kabootars (pigeons)
Just to stroll around and enjoy the people there
and best to photograph Mumbai (a city of 9 islands and a thousand faces)

Go there…Its worth it
