I have been to Annapoorna many times. If you are vegetarian and south indian, you will love this place. The food is awesome. The best part is the taste is consitent. I like each of the items, pongal, idli, adai. I never liked adai and pongal much. After eating here I started liking them. The murungai keerai adai here is awesome.
For those in diet also, they have akki roti, kelvaragu roti.
But the bad thing is they don't accept cards. you have to pay by cash.
Even at 10 PM at night, you get the food hot and tasty. The serving people are very courteous.
