Lunch is pretty good, but dinner is a bit pricey. Food has improved since it opened, as has service. I get the lunch option, which comes with rice and a salad (still not sure why they serve this...).
People in my group in the past have been unhappy with the authenticity of some of the dishes, but now it seems they warn people in advance if the dish is being prepared in a surprising way. I've had their chicken vindaloo, chicken tikka masala, and their paneer makhani, and each were good.
