I am surprised by the comments from Dave and the other person. The concept is very unique and getting Indian food in a fast food envoirnment is wonderful. I have had food there quiet a few times and find it very flavorful. If you are looking for Indian food, be prepared to get a little grease. The naan bread is not a good one till it is drenched in lot of butter and so is the case with other curries.
I don't think the sauces are out of the packet as it tastes really good. I like the korma the best. Also go for the mango lassi which is amazing.
It seems to be a little pricy but the quantity of the food does justice.
You cannot compare Tandori with a five star restaurant food but for a food court Indian food,it is great.
