I am from Mumbai, Maharashtra. I am visiting Juhu Beach from last 10-11 years(since my childhood). The beach is very much crowded and dirty as it was before. Nothing has been changed. It gets more dirty in rainy season. I will recommend you to do not walk there with naked feet. Sea water is also dirty because sewage water. I do not feel pleasant while hanging out there. The food is also very much expensive there. Typical chaat(snacks) cost you around Rs. 30-50. I hope BMC will do something seriously about these issues.
