Either Taxi is safe for transportation or not, any scams by them?
Taxi is safer then personnel car
Which market is best for baby & Kids shopping?
Sorry i am not married. Therefore no idea :D
Please advise the safety precautions?
Never resist with snatchers if you come across to them, give them whatever they want. You will be safe this way only, Unfortunately :(. Don't say them that i don't have mobile, wallet etc as they are well aware of the fact that people can't survive with these things. Its better if you can carry one cheap cell phone (if available) with you. Try to keep heavy cash in your socks or at some other place where you think its hidden.
Which areas we can visit at night safely?
Clifton Beach and above mentioned food streets.
Which areas we should not go due to Forces Operations?
Don't worry, they will not allow you to go there and your taxi driver will be aware of those places.
