If you enjoy classical or just want a bit of respite from the teeming pace of the city, I strongly suggest checking out Meikyoku Kissa Lion in Shibuya for an "only in Japan" kind of experience. It's quite surreal. It was est. in 1926, scorched in WWII air raids, and rebuilt in the 1950s in gothic style architecture that somehow transports you from present-day Tokyo to 1940s bombed out Berlin... it's as if you've just stepped off the busy side streets of Shibuya and entered into some sort of ruinous post-war underground European art cafe run by an eccentric Japanese baroque music lover! He serves only two menu items: coffee and something called a milk cream, which is sort of like a frothy hot egg cream and it's surprisingly good. The atmosphere inside is church-like with rows of cushioned pews covering the ground level and balconies on the upper accessed by a very narrow and winding old staircase. The acoustics inside the room are just incredible. Apart from the music emanating from the vintage Hi-Fi speakers, there is absolute silence throughout the building- total serenity! The owner constantly shuffles through his vast record collection at the front of the room, tinkers with the amps, drops the needle on a record and then quietly introduces the music by whispering in Japanese through a hushed microphone, almost as if you were listening to a classical radio station. It's very soothing and there were many Japanese college students spread out in various nooks, deep in study. It's just a really unusual setting to happen upon in the middle of Tokyo... I highly recommend checking it out; it's a great way to spend an hour or two on a rainy afternoon.

Some photos I took w/ my phone camera a few years ago... looking down at the beautiful 3D speaker setup from the upper mezzanine:





And from ground level...
