I was not much amaze with Mumbai might be not because of rain. But beauty comes with night when the place lit with colour and people.
Bars, cafe and nightlife is much enjoyable.
Riding bikes on road in night another great way to explore.
Kali pili taxis are budget friends and don't forgot local of mumbai which is necessity for it's people.
Explored mumbai for 1 night and can say i have enjoyed much with new city and way of life.
