As a coastal city, Mumbai has many beaches along its western coast.. Juhu Beach is one of the famous beaches of Mumbai for its street food(check my post on stalls at Juhu beach here) as well as popular Italian restaurants. On the southern end of Juhu beach are many luxury hotels and apartments. This beach is also popular for watching aircraft as planes from Chhatrapati Shivaji International Airport usually takeoff directly over the beach towards sea.
