how is food at stephen's hostel i.e taste, hygiene etc
Yes the food is decent but of course it will be different from what you have got till date at home cooked from your mother or someone who cares for you. At hostel, there is no special caring. The food is cooked in mess for everyone. So the hygiene can't be guaranteed. But as per the reviews the food is decent enough at Stephens college. But anyhow your career and college choosing is prior to hostel type and these factors.
