Hello malaykmehta,
The Indian community in Sudan is HUGE.....they have Indian clubs and schools in the capital and MOST major cities (especially Port Sudan, Medani and El Obeid). In the capital the majority live in Omdurman and they lead the market in textile and the gold industry, with plenty of outlets for their business in Omdurman and Khartoum's Parliament market area (Bombay Bazaar, Mumbai Textiles etc...just to name a few)...
There are also a large number of Indian food outlets and most supermarkets now sell various foodstuff related to your culture based on the large number of Indian's living here...
I hope this helped...
