I've been ordering delivery from here on a monthly basis for a couple of years now. I loved the food when I lived in SW and still do now that I'm living in SE. I can't speak to the majority of the menu, and I can't say I like their vegetarian dishes much (there's not a ton of flavor), but the staples, namely chicken masala and chicken tikka masala, are awesome.
Delivery is always prompt and courteous. The food isn't super cheap, but I find the portion size to be quite good - I usually get at least two meals out of one entree, so the price doesn't bother me.
As a disclaimer - I always get medium or hot spice, with "hot" being very spicy.
