Mumbai: Beaches, Taxis and Buried Treasure

Arrived at Mumbai for a week long visit. The hotel is on the beach, which was quite full earlier on, however this photo seems to make it look fairly empty:

The front of the hotel is full of taxis, however not all of them seem to be reliable:

At the back of the hotel is an area of palm trees. I wonder if this is where the treasure is buried (not quite a 'Big W')?
