Amma canteens, known as "Amma Unavagam" in Tamil, offer breakfast, lunch and dinner even during lockdown.
The Greater Chennai Corporation, which runs over 400 Amma Canteens in the city, on Thursday announced free food to people at all its eateries till the lockdown ends.
Days after the food items were made free for people in the Western cities of Coimbatore and Salem, the GCC in its twitter handle said under Chief Minister K Palaniswami's ''order and guidance'' all Amma canteens in its jurisdiction will provide free food thrice a day till the lockdown ends.
Local Administration Minister SP Velumani tweeted that the Chennai corporation with the largest number of canteens in the city has made food free in all its 407 canteens until end of COVID-19 curfew.
"Under Hon'ble CM's guidance, our govt strives to best serve the needy alwys,!" he said.
Sources told news agency PTI that per day, at least Rs 17 lakh is the cost of food served in the 407 canteens in the State capital and volunteers have expressed willingness to foot the bill.

On April 19, Mr Palaniswami announced free food at all Amma canteens in Salem district, his native place, and said that the AIADMK's local units will bear the cost.
In Tamil Nadu, there are 600 plus canteens and in Salem district, 11 are functioning in the Corporation areas and four in municipalities including Edappadi, the home turf of Chief Minister Palaniswami. Launched by former chief minister late Jayalalithaa years ago, the Amma canteens, known as "Amma Unavagam" in Tamil, provide breakfast, lunch and dinner even during lockdown.
