Jhighatigare,

 The owner is not going to increase his business by appealing to Indians at the expense of Nepalese or by appealing to Nepalese at the expense of Indians. Why don't you explain to the restuarant owner that it is in his best interest for his business to create a sign board that appeals to both Nepalese and Indians (and even Pakistantis for that matter).
