There is something reassuring about finding an East Indian food stall right within a gaothan, or a village for the community. It's a bit like finding a dumpling place in the middle of China Town in western cities, since the authenticity of what you're going to eat is more or less guaranteed. But what's even more reassuring is when you reach the said stall at around 8.30 in the evening and find that they have sold out almost everything they serve - such as chicken and potato chops, vindaloo and other curries - after they opened for business only at 7 pm. It puts an added stamp of authenticity on the fare. And that's exactly why we approach the last-remaining buffalo tongue roast (Rs 60) at East Indian Fast Food, which is essentially a cart in Kolivery village in Kalina, with a great degree of confidence.
