As I mentioned already, Chinese ppl know Dosa and Parota already. We can find several small carts selling Dosa & Parota. Not sure how they came to know.
There are very few indian restaurants in Shanghai.
There is a Punjabi Dhaba here. We will be surprised to listen the latest Hindi songs in this restaurant. You can speak Hindi and find few Indians here. Surprisingly, people from Germany & England regularly come here for weekend parties.
And also, there is a pakka South Indian restaurant near by my hotel called "Indian Kitchen". Owner can speak very good Tamil, all the south indian dishes are available here, but very expensive.
There is a Gujarati people's house near by my office, where they serve all kinds on Jain food. So, few Jain people in Shanghai come here regularly for their Lunch.
