I highly recommend coming here for their lunch buffet. It's not huge and the selection is kind of limited, but they make up for it with quality.
The staff is awesome and even knows me at this point. They're always friendly, and are willing to go above and beyond to help you out. They're also super aware of what they're serving, so they can help me sort out my allergy needs.
They always have a few traditional choices you'd expect like chicken Tikka masala and a vindaloo. They have pakoora, samosas, and a fried naan that is just spectacular. The food has never tasted old, and they're constantly refreshing things. They also check on how you're enjoying things, and will help with suggestions if you're looking to make it a bit spicier. Every Tuesday I have been there, Mushroom and Paneer Masala has been available, and I have to say it's the best I've had in Madison.
$9.95 is a really great price for lunch, and you get a 10% discount if you pay cash.
