Thanks for posting. The restaurant is not producing pure Chettinad food. It's fairly honest about this. If you were in Chettinad and you went to a restaurant you wouldn't expect pure Chettinad food either. The menu looks tempting. If it tastes good and you like the staff, my top priority would be to work my way down the whole list. Feeling quite homesick looking at that menu... For authenticity: yes to heat, yes to pepper, yes to coconut.
