If going for lunch,try the students cafetaria located on the first floor of the cafetaria besides the bookshop and behind community health centre.it closes at 3pm sharp. Moussechoclate is speciality
Tea is awesome while you would also like Fruit cake. Try Fruitchaat and Cholay as well. However don't pick up additional things as you have to pay heavy bill at the counter then.
Where else will you find healthier food? Lol. Reasonable prices. Awesome desserts :) best part is that it's open and safe even when the whole city is shutdown :)
