Tsukemen(called mori-soba in this shop) with wonton and seasoned egg. Also a slice of pork at the bottom. Wonton is good but pork and egg are so-so. The noodles are cold by default, but you can also choose hot noodles for Tsukemen, which is probably a better idea in this weather. This shop is a branch of the very popular Taishoken in Higashi-Ikebukuro.
