বানারসী কুঠি

My one and only trusted saree shop in this world. My mother introduced me to this shop as it was related with her every occassion. Now there are several outlets like B K Fashion, Benarasi Kuthi agencies etc. who claim to be the same organisation. But my confusion is whether all of them provide same quality and guarantee? I do not go to any other stores so I am not able to compare.
