The house speciality at this eccentric shack-like joint in the shadow of Tokyo Sky Tree is te-uchi udon (handmade wheat noodles); other dishes to sample include tori-ten (chicken tempura) and kurokke (deep-fried potato croquettes). There's homemade umeshu (plum wine), too. Look for the orange awning out the front.
There is a ¥200 cover charge in the evening.
