Sardar Vallabh Bhai Patel Road is one of the oldest lanes in South Bombay, and home to some of the oldest music stores in the city. Take a walk down here, and you’ll immediately be walking down a memory lane. Do stop by R.S Mayekar {the shop from the 30s}, that still repairs old sitars. They also have the old and classic stores like Laxmitone Magic World, Singh Music Stores, and Haribhau Vishwanath Music Industries.
