Got back a couple of weeks ago. What a city.
In the end we didn’t visit an audio bar, but we did see a cat cafe !
Visited Tower Records in Shinjuku and got dragged into a mesmerising Don Quijote store where we spent far too long and for some reason I emerged with a lovely rubber chicken pen that squeaks when you squeeze it.
Highlight of the bars was the abovementioned Cadiz bar. Mr. Yokata was the epitome of the professional cocktail barman in white coat and pompadour, down to the flourish as he clicked off the pen with which he handwrote the bills. Andrea had a gimlit (excellent) and we had a great chat with him about Sherry, drank some of his recommendations (including an amazing light Amontillado from Manzanilla) and looked at his photos from his visit to Cadiz last year. He has every spirit under the sun as well as sherry, including a wide range of whiskies. If you go there, call ahead and make an appointment as it is very small and he gives preference to his regulars.
We visited the Hamarikyu Gardens (our hotel overlooked them) and the East Gardens of the Imperial Palace, both recommended. We rushed through the Nezu Museum on our last day, absolutely fascinating.
