For 80 years, a little provision store in Royapuram has been selling, among other things, their own special mango ice cream. Over the years, the only thing that's changed is the modest price, now Rs 10 a cup. The taste has remained the same. And so has the demand. Many big ice cream brands may have hit the market. But in north Chennai, people still swear by Mango Ice Cream at Kunhiraman's.
