In my opinion the first time you useyou eat the street food & drink you can get sick but after that you get habituated ofused to it.Second The second thing to be aware of is that if you does not want to use street food & drink ,you you can use other costly places where all the food & drink is made cleanly & tidy.It It depends on you, otherwise street food is good in taste & i also belong to india. I live in India and it doeshas not effectaffected me once.
