If Kannada can also be a Carnatic raga, then Mountbatten can refer to the veteran running that canteen alongside the music venue. At 87, Mani, with a prefix that is the name of India’s last viceroy, is busy entertaining guests at his Chennai cafeteria that can go quiet once the Margazhi season ends by mid-January. For three weeks now, his special delicacies have enriched concert freaks with an experience as delightful as a Todi alapanam or taniyavartanam on stage. So much for his lip-smacking Deccani dishes at the thatched pandal by Sri Parthasarathy Swami Sabha in downtown Mylapore.
