I would have to place Chaat Cafe near the top of Indian places close to campus. A clean, pleasant place with too much seating (every time I've gone at least) and friendly staff (of one or two). I am not an expert on Indian food, but I do know that it offers plenty of the typical choices to keep me happy, and if you go with someone in the know on Chaat, you'll likely find something to love.
The prices are a dollar or two above Naan N' Curry, but in return it offers an unobtrusive atmosphere and you don't smell like smoke afterward. They have forgotten to bring part of an order once or twice, but it is not a big problem and easily remedied. I highly recommend it for a pleasant dinner when craving Indian food.
