Where is leopold's pub in mumbai?

i'm Santhosh K S from Bangalore..i'm pretty much impressed by reading the book 'SHANTARAM' by Gregory Roberts.So I want to see the LEOPALD"S pub and the HAJI ALI mosque once...so any mumbaite can answer my question i think.It will be very helpful if some body can give me the landmark,the address and the shortest way to take from airport.
