I visited Titans Tap Room in Otsuka, Tokyo in September 2016
Once we were close the place was easy to find. The whole street outside the tap room was filled with people. Standing in groups. Chatting. Drinking. A small bar had been set up outside where two different beers on tap were served. Inside the selection was a lot bigger. The lines for both bars, inside and outside, were long. The bartenders very busy. I recognised a friend working behind the bar out on the street. I got in line, wanting a beer.
