Daisangen/Kinshicho
大三元/錦糸町
First place in Sumida-ku. Good mid-price Chinese about 5-10 mins walk north from Kinshicho Station on the JR line. Also accessible via Hanzomon Line. Excellent suratanmen - but very peppery. Thick broth with somen noodles. Very flavorful full-length negi cuts. They have it with and without the noodles so be sure to specify. Many interesting things on the menu (the ones I could read) but it is hand-written in very-difficult-to-read script with very little kana - bring a someone who is a good experienced kanji reader. Many couples in there for a lunch on a Sunday - there was a line inside and outside the shop.
