Hotel Aaryas, Thiruvannamalai

A nice vegetarian restaurant located less than 100m from the Central Bus Stand, Thiruvannamalai.  From the bus stand, you have to walk towards Gandhi Statue / Bazaar Road and you will see this restaurant on your right.
We had south-Indian breakfast.  The food was tasty and the service was prompt.
There is an A/C restaurant on the first floor, but that opens around 11:00AM.
Definitely recommended !
