Authentic South Indian cuisine at very cheap prices. What more could you really ask for? I can taste the masala dosai right now as I'm writing this review. The only thing this restaurant can improve on would be service. Frankly, the service during my visit was typical of service in other Indian restaurants: very curt interactions with restaurant workers who are simply there to take your order and put the food on your table. Just embrace it for what it is.
Also, this place literally is a hole in the wall. Don't come here expecting a fancy place. Come here expecting great South Indian food that you typically won't find at your run of the mill Indian restaurant in town. Oh, and come for lunch as opposed to dinner. The value is tremendous.
