Frankly there aren't any good ones anymore. Welcome was the only place where you could get the best south indian food but they closed down a few years ago..Now you can try Aryas, Maharaja, Vasandra Bhavan and Garden Annopoorna.. They are just fine.. If anyone else here knows where I can find the best South Indian food, please let me know bcoz I just love dosas, idlis, vadas, uttupam, iddyapam, apam etc..
