Haha lol i gave a call twice and lady keeps on saying owner is busy with some shit . I will tell you what why don't you print this thread highlight each post where people have protested against  him . Make few more copies of the print and go to restaurant hand him and few other nepali customers whoever are eating over there.

Also try finding out few nepali organization around that location and see if you can get those people to talk with this owner if you are serious about it .
