As the fourth most populated city in the world, Mumbai is a bustling city of extremes. The city can be spiritually calm yet exuberantly flashy at the same time. Once known as Bombay, Mumbai is the commercial and entertainment capital of India. Home of the thriving Bollywood film industry as well as the center for many important financial institutions and corporate headquarters of India, Mumbai has everything you\'d expect from a Metropolis, plus a dose of Hindi culture mixed in.
