Other places to visit includes: Basilica of the Sacred Heart of Jesus(church), Rock Beach, Sri Aurobindo Ashram, Immaculate Conception Cathedral(church), Varadharaja Temple and many more.
The best thing you can do is hire a scooty or bike (About Rs 400 for full day ), go on and complete your wanderlust. Many food outlets and market in Mission Street are good "ADDAs" for hanging out and shopping.
Now for good and delicious food at cheap rates, I will definitely refer the one and only Punjabi Dhaba in Mission Street. This is where we had our relishing dinner (cost around Rs. 100/person). In spite of that this white town designed in French architecture is a must watch. There is a lot of variety of unmatched continental cuisine which will make you forget that you are in South India.
The first place that knocks your mind when you hear about Pondi is 'Rock beach.' This place has a Gandhi statue and where crowd of bazillions is always there (I don't know yet). But the place contains some swag energy which always brings out a good DP and a moment of peace and tranquility. After more foods & drinks and dancing on "DESI" turn-on songs, some of us came here and clicked the amazing pics at 4.30 a.m. It came so good that even crabs were peeping out of their crevices to watch it.
