I went here on Groupon, but their prices are soooooo cheap you don't need to wait for that special deal.
It's a non for profit located in a temple. It has a very quite atmosphere that you'd expect temples to have.
The buffet is served to you as many times as you wish and they have a variety of desserts (chickpea flour cookies!!!) and drinks (tamarind juice is an interesting choice but very strong in taste).
I'd definitely come here again esp when I feel like saving money and eating a good Indian food.
