I found this restaurant lovely with very friendly staff and authentic South Indian food.
With my experience at eating in Indian restaurants in US soil(which is many) I have picked up the knack to choose the dishes based of the staff/cook.
As I realized the staff is from south I made a conscious effort to order accordingly and the dishes turned out great.. below is the gist of experience.
Best dishes: Dosa, sambhar, rasam, biryani
Authenticity: 9/10
Service: 9/10( they are a little easy during lunch buffet, at dinner you feel as though you are eating at your grandma's place)
Hygiene:8/10
Ambience: 8/10
*Tip: for dinner they have some attractive offers such as buy one dosa get one free on Tuesdays
