Southern Railway — catering in kovai shatabdi express by north indian caterers

Address:

Chennai, Tamil Nadu, 600130

I have travelled quite a few times by shatabdi express between chennai and coimbatore. I observe that the catering is done by some north indian agency who has employed mostly north indian persons who cannot understand a word of tamil. Also, it is shocking that lunch / dinner served is nothing from south indian cuisine. Once, i got dal, bengan bhaja in lunch. Another occasion, i was served paneer paratha and typical punjabi gravy. I wonder if such catering is done in any of the northern railway trains, where passengers are served sambhar, rasam or kootu.
Please look into this complaint and stop serving north indian dishes which we find extremely unpalatable. After charging nearly rs 200/- donot insult us like this.
