Taj Mahal Imports is the premier South Asian supermarket in the DFW area. Basically whatever your needs are, they can meet them. Besides the typical grocery store selection of fresh produce, breads, spices, instant meals, etc, they also sell items for pooja, jewellery (glass bangles and the like), magazines (India Today, Filmfare, etc), henna paste, home decorations, and more. In the back is their Chat Corner which is fairly well known around here; the chaat's quite good, and they also have pani puri as well as full meals with roti etc., and also kulfi and a variety of cold drinks. There's satellite TV for you to watch while you eat.
The selection is the best thing about this place; do check your labels though before you buy anything, some of the expired stuff is not moved out of the store for months afterward!
The store draws quite a crowd around 7 or so. There is no minimum required for credit card purchases.
