I like Chennai, or some place else in India. India is where this lovely game originated, as far as I can tell, and Anand has been one of the great gentlemen of chess. Also, Indian food is spectacular! Mr. Carlsen should enjoy such a place to play the world chess championship
Anand vs Carlsen : Where is the most suitable, best, ideal venue for the match?

All chess events should ideally be held in places from old Austria-Hungary with romantic names that had famous chess tournaments, like Mährich-Ostrau or Teplitz-Schönau.
Obviously, Chennai is not the most suitable, best, ideal venue for Anand - Carlsen match. I would suggest Singapore, Tokyo, Beijing, New York, London, and Paris.
Singapore comes first.
