Tips on how to find a good noodle restaurant
Do not go to a noodle restaurant that serves all kinds of noodles!
らーめん(ramen) noodle is not Japanese origin. It has a completely different soup base (usually Chicken and Pork) from うどん (Udon) and そば (Soba) (usually fish base).
Thus a good らーめん(ramen) noodle restaurant does not serve the other two types of noodle and vise versa.
