I've visited here during lunch and dinner. Their lunch buffet is modest but worth the price! There are meat and vegetarian options, with each being flavorful. Their dinner options are also delicious. I especially love their Murg Makhani & Chicken Tikka Masala! The staff are attentive and friendly. Wait times are minimal. However, having to pay extra for rice during dinner seems a little silly to me. That appears to be common in Phoenix, though.
I recommend India Palace for their high quality of food and friendly service.
