Omoide Yokochō Memory Lane
Tokyo has hundreds of thousands of fancy restaurants and bars serving fine and high-quality meals, but for more unique booze experience, Izakaya alley (Yokocho) is an amazing dining option.
Izakaya is Japanese style bar/gastropub serving drinks and Japanese food or snacks (at relatively cheap price usually). Izakaya bars are especially popular among salary man and locals to hop in right after work for a couple of beers. Izakaya alleys are old fashioned, smokey narrow streets clammed by small Izakaya bars. Some of Izakaya are very tiny and have only a few seats.
Sitting next to local and sipping a glass of Sake with authentic Japanese dishes/snacks could be a whole new experience for foreign tourists rather than dining at high-end bars. There are several atomospheric Izakaya alleys and drinking districts in Tokyo such as Shinjuku, Shibuya and Ueno.
One of the best ways to explore the Social culture in Tokyo is joining Social-hopping tours! A lot of local Izakaya might be hard to find or enter for first time visitors, but the local bar hopping tour can take you to hidden bars and Izakaya and show you the real drinking culture in Tokyo!
