So, this review is based on my experience with the lunch buffet. On food alone, I would have rated 2 stars because it all seemed a little old at that point (like it had been out for a while), but I came in at the end of lunch.
The rest of the experience was great, though - it was a cheap meal, it was fast (I was alone, eating on my way to a meeting) and the service was unobtrusive but consistent. My water was always full and I had as much naan as I wanted.
A note: a lady at a nearby table was complaining that the food was all too spicy. I am pretty spice-averse, and found everything to have heat but didn't mind it. So, if you're like that lady and have a zero spice tolerance, beware. Maybe don't eat indian food though, you know?
