Great deal at late night (half off certain entrees), but it's a little loud at night. The service is generally bad, they don't refill your water, and they don't always even get your order right. The food is also very inconsistent. If you order an entree with a medium spice level, and order the same thing on another day, you definitely will not get the same thing twice.
The lunch buffet is always a good option too, because you're not stuck with one entree. If one of the entrees isn't as good that day, you can just move on to another dish. Also, unlimited naan is a really really good deal!
