Automated beer dispenser

I spotted this contraption in a teeny, tiny little restaurant in Tokyo. It pours the perfect glass of beer at the touch of a button.
The dispenser was situated right next to the only table in the place. You serve yourself and just shout over to the kitchen when you refill your glass, so they can keep track of what to charge you.
Another only-in-Japan thing. (One of many.)



p.s. this is my first video clip.
