It has a bit small entrance located along with Shinjuku Kuyakusho avenue. Amazing enough that all clerks are female ^^; The think Tori Paitan soup is so delicious that I cannot resist drinking it all. Variety of foods available so if you cannot pick one, try either soy sauce or salt based Tori Paitan Soup Soba.
