We've been here plenty of times for lunch and dinner. We prefer the lunch vegetarian thali. It's a great value for money. You get a mung dal soup to start and then a plate with rice, naan, 2 vegetables, lentils, raita (yogurt) and a dessert. Naans are hot fresh and soft, the spice levels are perfect on the vegetables. The raita is soooo flavorful I normally don't care for it but Dhaba makes some good raita.
I felt dinner was not much value for money. Portions were a little smaller than most other Madison area Indian restaurants and food takes a while to come out on the weekend nights.
