There is also a very nice little bar in "Shimokita" (that's how you can shorten the name btw -- don't say "shimo" because that means "dick" in Japanese).
Anyway, the bar is called Never Never Land (pronounced "Nebah Nebah Rando" in Japanese) and is run by two very nice women from Okinawa. The Okinawian snack food they serve is great and the unique Okinawa Sake will make you want to drink on forever.
Especially if you drink it as "sour" (my recommendation), you will be able to consummate quite a lot before you feel any effects. Then however it’s getting rather severe very quickly.
The bar can be found near (5 minutes by foot) the south exit of Shimokitazawa Station.
