I guess I'm not hating on this restaurant because I've never been to the bathrooms. :P
I have only gotten takeout from here (buffet for takout and dinner one time). Not the best Indian buffet ever, but good. If you're looking for spice, none of the buffet items are spicy in my personal experience. You can get buffet to go for the same price as lunch buffet--you can fill up a takeout container with food and also get naan to go.
My preferred Indian restaurant in Madison is Swagat on the restaurant, but the Taj is all right.
