Madras Curry needs update.
Absolutely. The next time you’re at your favorite Indian restaurant, instead of ordering Madras curry, you should ask for Chennapattanam curry. If the menu lists “Madras curry,” make sure you point it out to your server, calmly explain why it is incorrect, and request that the menu be updated. They will appreciate your care and understanding so much that they might even give you your meal on the house.
