The idea of a Bitcoin shop in a big city isn't something new, and a fair amount of them exist in countries throughout Europe, however in the US and other western countries chances are the interest in the Bitcoin aspect of the shop will probably be a bit lower than other places, but it will probably still exist. For some people running a shop like that would work, but I have no idea if it is practical in any way though.
although it is an old ideas but still i like this idea and i am welling to open a shope in market and do accept bitcoin for shopping but we have a problem that in our area still most of the people have no idea about bitcoin, therefore first we should introduce bitcoin to them.
