TAP PUBLIC: Craft beer in Seoul, Korea
It's unique system supprized me.
There are about 40 taps !
You pay for each 10 ml !
It means that you pour beer by yourself as small amount as you like.
So,you could taste a lot of them and find the one you like.
Restaurant is quite big.
You put this band on each tap everytime you pour beer.
And it records your beer bill !
