Defenetlly sagar ratna is a big name of south indian food. In south indian thali they are giving approx 12 types of watery sauces that is impresaive but at a north indian I didn’t like all insted of two or three. But in indian thali quantity is less but taste was good. If any one want to taste the all 13 types of water then sagar ratna is a good place. I like masala dosa of there they have totally different taste from others. I have tasted dosa in many places but sagar ratna’s is yummest one. They have lots of virety in indian and south indian etc.
