There are plenty of South Indian Restaurants as of now in Doha, If you really interested to start a restaurant, think of some ting which is not here.
I recommend to start Andhra Style restaurant with both Veg & Non veg.There are few Hydrabad restaurant and Hydrabadi Biriyani, I have not found even one 100% Andhra or Hydrabadi biriyani, it wii be Malabari style only.
