Are there convenience stores inside campus? Do students need to go out of the institute to buy what they need?

You can go outside campus to shop if you prefer, but there are plenty of options available within IITM itself.If you're looking for grocery, stationery or items of daily use, you can walk over to KK Departmental, Prime Mart, or Gramodyog.For a more mall-like experience, head to IITM shopping centre, which has around 20 shops for groceries, snacks and facilities. It even has a few restaurants.If you'd like food, the Himalaya Food Court is open till 1 am (not to mention the several messes, food court and eateries within IITM)For a midnight snack or piping hot tea, Ramu tea stall in Quark is open till 3am!There are many other eateries and facilities close at hand, so IITM can often feel a city within a city!
