Can I get Pure Indian vegetarian food or south Indian dishes in Shanghai?

There are many authentic indian restaurants in this city. You can go to Vedas Indian Cuisine. This one wins high popularity among local people and Indian tourists. I believe that you can also make some friends there. This restaurant also provides pure vegetarian dishes for you to choose. It's located at 3rd Floor, Shishang Qianzhan Mansion, No.83, Changshu Road, Jingan District. But I'm not clear if it is the southern indian style.
