We don't write in Hindi in tamilnadu,we write in Tamil. pani puri is not popular in tamilnadu neither is lassi and you can fly to chennai instead of going to kolkata and driving 27 hours . kathakali is kerala dance(end bit), in tamilnadu bharatanatyam is more popular(among classical styles).
would have been better if you had used India's map of India rather than some foreign version where top portion of India has been cut off.
was fun anyway.
