Hello Ashish,
Me and my husband,we are crazy about Indian food! And there's only one restaurant in Montenegro, which on the menu has Indian food ... but not very good. We chatted with the chef, who is Indian ... He said that he has a problem finding the ingredients to make Indian dishes. No spices, no Asian vegetables ...
As there are not many Asians in Montenegro, there are no shops where you can buy Asian food.
If you had a plan to open Indian restaurant in Montenegro, we welcome you.
But before that, make sure you have a good business plan!
Good luck :-)
