One must-see is Chowpatty Beach, not for swimming or sunbathing, but because it is one of the greatest people-watching spots in western fakirs and fakers walk on fire, sleep on nails, climb ropes in midair, or bury their heads in the sand; food vendors hawk kulfi ice cream as well as pan, betel-chew, and bhelpuri, a spicy local specialty.
Most people that try bhelpuri absolutely hate how spicy it is.
