I was craving for south indian food on a weekend so we went to Nilgiris for buffet lunch which is $11. For the price I think the options were reasonable, all south indian dishes. I only ate idlis, vadas, dosa and poori. There was no upma :( Overall the food was tasty.
Only thing I would complain about is the service. There was only one lady serving pooris and dosas which was very slow. There was a big group close to our table eating at the same time. So all the pooris/dosas would finish by the time the lady reached our table. That was kind of disappointing.
So overall I would rate this place 3 stars. Worth one time visit.
