Yurakucho’s “Ga-do Shita” is an area with many Izakayas and Yakitori restaurants hidden away literally underneath the railroad tracks. As a result, when you visit this area you can expect to hear the JR and bullet trains passing by above you. Most people traveling on the trains would have no idea what they’re passing over, but in this somewhat mysterious part of Tokyo lie some hidden spots.
We visited Ga-do Shita on a day after it snowed in Tokyo so it was quite empty, but it is typically packed with salary-men drinking away the night. During the summer time, everyone sits outside in the open space and it becomes very lively and loud.
Check out Yurakucho Nenohi if you’re in the area. We enjoyed it!
