Yurakucho station is one stop south of Tokyo Station along the JR Yamanote Line. It is also next to the glitzy Ginza district with all its high class shops, restaurants and entertainment. One of the lesser known attractions is a little street known as "Yakitori Alley". It’s underneath the railway tracks full of little tiny bars (yakitori-ya) where you can get a beer, some yakitori, and relax after a long day of sightseeing.
These bars are on either side of the railway lines below the tracks and are usually full of Japanese, occasionally a foreigner, but not so much.
