Kunugiya sits right in front of Exit 3 of Shinjuku-gyoemmae and serves house-made udon. The cold udon has a firm, chewy texture, and the noodles are as thick as tteokbokki. Customers pay by card at a kiosk outside the shop, then wait in line; on a weekend at 3 p.m. the wait was about 30 minutes. The inside of the shop is small.
