Let me list my qualifications first - I have lived (not just visited) in six different states in different parts of India, I have traveled extensively and tried Indian restaurants in 15-20 states in the US and, finally, I have tried 10-20 Indian restaurants in the Valley.
This place is strictly mediocre and chats (snacks) here, that everyone seems to be raving about, are made from out-of-box stuff. They lack freshness, flavor complexity, and are largely monotone, primarily of tamarind chutney. Kachori, for instance, is a sad imitation of a real Kachori which is typically crisp and with some filling. The menu is very limited and, for the quality of food and ambience, is overpriced for a self-serve corner eatery tucked inside a grocery store.
Finally, the owner at the front is indifferent at his best and rude if he has to talk to you. Servers, however, are efficient and courteous and they earn one star.
