Time Out says
Tsukemen is usually known for having pork, seafood, or even beef-based broth, but over here at Zagin Soba, chicken is all the craze. Serving up arguably the best chicken-based broth in town, the restaurant has a small and refined menu that will keep your decidophobia in check. The flavour is a given, but the broth is also light and creamy all at the same time, giving it a refreshing take from your usual tsukemen which tends to be on the heavier side of things. Zagin Soba often adds special time-limited items to the menu too, meaning you'll have all the excuses you need to go back time and time again.
