I am terrible at describing Indian food, but I still love it. I've been to almost all of the Indian lunch buffets in the area, and I think Haldi Masala is my favorite.
When you first walk into Haldi Masala, you don't really see much. It gives you a simple family restaurant vibe. They don't go over the top with decoration and presentation. If my memory is correct, you eat off of the kind of paper placemats that your child can color on. The spread isn't as big as some other Indian buffets in the area either. However, they make up for the lack of variety with flavor and passion.
The main thing I noticed about Haldi Masala's food was that it was a touch more spicy than some of my other favorite Madison-area Indian lunch buffets, and that was great news for me. They also had some dishes that I've never had before like crab curry, and some kind of chicken with cashews. I talked to the owner about how I liked the food, and he seemed very excited to tell me about the different recipes that they do. I think I will be here frequently on weekends.
A bit of a disclaimer: I had gone to Haldi Masala's lunch buffet on a weekday once, and it was just ok. I'm guessing that they put out better food for the weekend when there are more customers.
