Asagaya, home to many of the small eateries which I frequent often. Sugar Sake & Coffee is a small sake place just a few block or two away from the station. A great selection of sake is served together with small dishes, which can’t really be said to be neither Japanese nor Chinese, but maybe somewhere in between? You can get everything from sui-gyooza (boiled dumplings) to sashimi and lighter salads - and everything is quite delicious. Moreover, the owner is a gem, and will serve up both funky (in a good way) and surprisingly fresh sake. Also, make sure you ask him to whip up a fantastic little bowl of ramen before you head out.

  

Asagaya should be on you list, and this would be one reason why.
