I agree with you.In fact and Frankly speaking Food options at MAS are very-very limited.South food lover gets Decent food at high cost at-least But for other than South NO OPTION available.Even Coffee is either high priced or low qualityed (compare to few years back when very good coffee was available on all stalls).
Unlike other metros this station lacks food variety,good dining space and food plaza.
More to add:A full AC waiting room is created for Upper class passengers @Rs30/- for first Hr and 10 for subsequent hours.Very Bad:-(
