I've walked by this tiny rather dirty standing vending machine bar area under the JR Yurakucho tracks many times during my time in Tokyo but was never really interested in standing outside with a vending machine beer in hand...
There are about 5 vending machines in this small space offering beers and non-alcoholic choices.
And there I was with my 240yen 500ml beer (vs Supermarket 160yen or Convini 205yen)... across the street were waves of Japanese salarymen and OL's heading to Yurakucho Station...
There is a guy sitting in the back that offers small junk food type snacks...
At 9pm it was a pretty big salaryman crowd enjoying mostly One-Cup-Ozeki outside in the cold... There were quite a few smokers so if you don't mind it or just need a quick one to kill time then its a easy and cheap way to have a beer.
The bar actually neighbors the famous Andy's Izakaya ever so popular with the foreign crowd.
