Tomoecho Sunaba

In business along Sakurada-dori near Kamiyacho since 1839, this venerable soba eatery actually boasts a history going back to the 17th century, taking its name from a quarry used during the construction of Osaka Castle. Run by the same family for five generations, Sunaba's speciality is a broth mixed with yam, first proposed by the restaurant's third-generation 'master'. Delivered directly from contracted farms, the yam adds stickiness to the dip and makes for a harmonious combo with the thin noodles. Definitely one to power you up on a hot summer day.
